Reflection example 2

A leaf appears green

Absorption example 2

A leaf captures every color wavelength except green

White light

All of the colors combined

The sky appears blue because

Blue wavelengths are smaller and reflect easier

Frequency

How often a vibration repeats itself

Transmission example

Light shines through a window

Gamma Rays

Smallest rays (smaller than atomic nuclei), make dangerous radiation

Radio Waves

Sound waves. The largest wavelength (lowest frequency) constantly around us

Transmission example 2

Sunglasses can dim sunlight, but it still passes through the lens

Ultraviolet Rays

Sunlight

The color you see

The color that is reflected back to your eyes

Wavelength.

The distance between waves.

Amplitude

The maximum height of a wave from rest

Electromagnetic Spectrum

The range of wavelengths in the electromagnetic field... From huge radio waves to tiny gamma rays

Visible Light

The range of wavelengths that includes the colors we see.

The color black

When all light is absorbed and nothing reflects back to your eyes

Absorption

When electromagnetic waves of light are captured by an object

Refraction

When light bends because it moves differently through one medium/object than another

Reflection

When light bounces off of an object

Transmission

When light passes through an object

The color white

When no light is absorbed so all of the colors reflect back to your eyes

Refraction example 2

Your feet look big and wavy underwater

Different temperatures light waves are

different colors

Lower amplitude waves mean the light has

less energy and dull colors

Longer wavelength lights mean the light has

lower frequency and warmer colors

Higher amplitude waves mean the light has

more energy and brighter colors

Refraction example

the broken straw image
