17
Q

Photon

A

21
Q

Reflection

A

Occurs when a wave bounces off of a boundary or object that changes direction, but stays in the same medium.

22
Q

Refraction

A

The change in direction and wavelength when a wave moves from one medium to another.

23
Q

Ultraviolet Waves

A

Light that has shorter wavelengths than visible light.

24
Q

Period

A

The time it takes to move through one cycle

25
Q

Which type of visible electromagnetic waves deliver the highest amount of energy? Red,Yellow, or Violet

A

Violet

2 - (A) gamma waves (B) radio waves (C) visible light

30
Q

The electromagnetic spectrum arranges light rays according to which of the following characteristics?

A

wavelength, frequency, and energy

31
Q

Each element has a unique ‘light signature’ because the electrons release photons of light when they drop back to their resting energy levels.

A

True

32
Q

In the demonstration where the glass rod (dropper, test tube, etc.) disappeared, there was no distortion of the lines from the index card when viewed through the beaker. What does this observation tell us about the illusion?

A

That light from the index card does not refract as it passes through the beaker, liquid, test tube, etc
