Wave energy

Intensity

A sound wave is the amount of energy the wave has. The greater the amplitude of the wave, the greater its intensity

Prism

A tool that refracts two separate WhiteLight into the colors of the visible light spectrum red, orange, yellow, green, blue, indigo, violet

Longitudinal

A wave that moves in the same way as the disturbance

Transverse wave

A wave that the disturbance moves at right angles to the direction the wave travels

Mechanical waves

A wave that transfers energy through matter

Polarization

A way to filter invite so that all the waves vibrate in the same direction.

Gamma

EM waves given off by radioactive atomic nucleus. They have very short wavelengths, very high frequency, high-energy and are very penetrating. The EM waves with frequencies 3×10 to the 19th power . Some uses of gamma radiation or sterilizing food in medical equipment, cancer treatment. Gamma rays damage cells cause so mutation, and or cell death

Wave

A disturbance that transfers energy from onr place to another

Concave lens

A lens that is thinner in the middle and sicker at the edges. It curves inward and causes an inverted Image past it's focal point. The virtual image is a Brighton smaller than the actual object

Sound wave

A longitudinal wave that is produced by vibrating object and travels through matter

Convex mirror

A mirror with a surface curves outward. The

Medium

Anything a wave travels through

Re-fraction

Bending of a wave when it passes through a new medium. It occurs because the speed of the wave changes.

Wave speed

Can be calculated by multiplying wavelength times frequency. It is measured in m/s meters per second

Absorption

Disappearance of an EM wave into a medium

Focal length

Distance from the center of the linens or mirror to its focal point

Radio waves

Electromagnetic waves with the longest wavelength and lowest frequency. Some uses or radio, TV, studying space, and cordless headphones. Radio station numbers are there frequencies. 98.7 the beat. Frequencies are 3×10 to the ninth power hz. For comparison, the wavelength of radio waves would be approximately between the length of 3 football feilds and 10 feet long

Concave mirror

Emir who surface curves inward producing a reflected image is enlarged

Vacuum

Empty space with little or no particles. Sound waves cannot travel in a vacuum

Sound travels faster the dancer the medium

Fastest solids slowest gases. This is because the particles being closer together in solids.

sound

Longitudinal wave that is produced by a vibrating object and travels through matter

Opaque

Materials that do not allow any light to pass through it. You cannot see through opaque materials

Trans parent

Materials that transmit some light to pass through it but not enough for a clear image.

Amplitude

Maximum distance a wave travels from its resting point. The distance from crest or trough to its resting point

Interference

Meeting in combining of waves.

Mach #

Number that compares the speed of a sound to the speed of an object. If something travels faster than sound it breaks the sound barrier producing a sonic boom

Compression

Part of a longitudinal wave that particles of the medium are bunched up or squished

Rare fraction

Part of a longitudinal waves that the particles in the medium spread apart

Image

Picture of an object form by waves of light

Over a period of time

Sounds above 90 dB can cause hearing damage. Sounds above 140 dB can be painful and sounds above 130 dB also cause hearing damage

Diffraction

Spreading of waves as it passes through or around an obstacle

Visible light

The EM wave energy with frequencies between 4.3×10 to the 14th power between 7.5×10 to the 14th power Hz. Some uses of visible light are vision , Illumination, and photography. From lowest to highest the colors of the visible light spectrum are red, orange, yellow, green, blue, indigo, And Violet.

Electromagnetic spectrum

The classification of electromagnetic waves by the wavelength or frequency

Wavelength

The distance from one point on a wave to the same point on the next wave. It is usually measured from crest to crest or compression to compression

Microwave

The electromagnetic wave energy with frequencies between 3×10 to the ninth power between 3×10 to the third power Hz. Some uses of microwaves are microwave ovens, cell phones, GPS, radar, and satellite communication.

Crest

The highest point in a transverse wave

Pitch

The highness or lowness of a sound. It is caused by the frequency of the soundwave - high frequency - high pitch, low frequency/low pitch

Trough

The lowest point in a transverse wave

Transmission

The passage of an EM wave through a medium.

Doppler effect

The perception of the change in pitch that happens when the source or the receiver is moving

Sound

The perception/interpretation of a sound

Focal point

The point at which a parallel lightwave reflects from a concave mirror or convex lens and comes together

sonance

The strengthening of a sound wave by constructive interference

Optics

The study of light, vision and related technology.

Radiation

The transfer of energy by electromagnetic waves

Sound travels faster through mediums with higher temperatures

This is because the higher the temperature the faster the particles move

Scattering

This spreading out of light rays in all directions as particles reflect and absorb

Electromagnetic wave

Transverse wave produced by the motion of electrically charged particles. They do not need a medium to transfer energy. They travel through a vacuum at 300,000 km/s. Speed of light

Decibel

Unit of measure for loudness/ amplitude/ intensity

Ultrasound

Used in medicine to break up kidney stones, to observe organs and fetuses and Doppler ultrasound can be used to observe the movement of fluids in the body

Reflection

Wave bouncing off of an object or Berrier

The relationship between wavelength and frequency

Wave frequency increases wavelength decreases. When frequency decreases wavelength increases.

Units of measuring pitch/frequency

Is Hertz. (Hz). A hertz is one complete wavelength per second

Frequency

Is the number of wavelengths that pass a point in one second

Destructive interference

Is when the energy of one wave subtracts from the energy of the other

Constructive interference

Is when two or more waves add together it makes a large wave from smaller waves.The waves are said to be in phase

Humans can hear

Pitches between about 20 Hz - 20,000 Hz. Soundwaves below 20 Hz are called infrasound. Sounds above 20,000 Hz are called ultrasonic
