polorization

(applies to transverse) cause group to be divided

destructive waves

(causes node)

What is the speed of light

3x10^8

What side has the highest frequency/high energy/short wavelength

Gamma

What side has the lowest frequency/low energy/long wavelength

Radio

True/False:The higher the frequency, the more dangerous the electromagnetic wave.

True

In a photographic darkroom, red light is used while developing the photographic film. What is the best explanation for using this light instead of just leaving the lights on in the room?

Visible light is what creates the image on the film in the first place. Low energy red light doesn't have enough energy to change the image already preserved on the film when the picture was taken.

Diffraction

a beam of light is spread out as a result of passing through a narrow aperture or across an edge, typically accompanied by interference between the wave forms produced.

refraction

change in direction of wave due to a change in its spread to a different medium

Light behaves oppositely to sound waves. When a light wave enters a more dense material, its speed will...

decreases

Light speed behaves oppositely to the speed of sound when changing materials. When a light wave changes material from water to air the speed of light will...

increase

In order to show light acting like a wave, the experiment would need to show that light exhibits this wave property that doesn't happen for particles

interference

Diffraction happens when...

light bends around a barrier

Polarization happens when...

light is filtered so that only parts moving in the right direction are allowed through

The photoelectric effect experiment showed that light can act like a _________________ because it can _____________ an electron.

particle, knock off

Waves can do the following things

reflect, refract, diffract, interfere, polarize

Particles can do the following things

reflect, refract?

Double split experiment

wave, interference, diffraction light and matter can display characteristics of both classically defined waves and particles
