Waves test

Question 1

Amplitude

Answer 1

The height of the Wave

Question 2

Compression Wave

Answer 2

A longitudinal wave propagated by the elastic compression of the medium

Question 3

Crest

Answer 3

Top of the wave

Question 4

Frequency

Answer 4

The rate at which something occurs or is repeated over a particular period of time

Question 5

Medium

Answer 5

Substance a wave travels through

Question 6

Answer 7

An elastic wave in the earth produced by an earth quake or other means

Question 8

Transverse waves

Answer 8

A wave vibrating at right angles to the direction it is traveling

Trough

Answer 9

The lowest part of the wave

Question 10

Wavelength

Answer 10

The distance between a successive point on the wave

Question 11

Artificial light

Answer 11

a light source other than the sun

Question 12

Diffraction

Answer 12

When a wave is moving the same medium, but bends around an object

Question 13

Electromagnetic Spectrum

Answer 13

The range of wavelengths or frequencies over which electromagnetic radiation extends

Question 14

Electromagnetic waves

Answer 14

Different wavelengths that do not need a medium to travel through.

Question 15

Infrared Rays

Answer 15

rays with a wavelength just greater than that of the red end of the visible light spectrum, but less than microwaves.

Question 16

Light

Answer 16

The natural agent that stimulates sight and makes things visible

Question 17

Photon

Answer 17

A particle representing light or other electromagnetic radiation

Question 18

Prism

Answer 18

A glass or other transparent object with refracting surfaces at angels that separates white light into a spectrum of colors

Question 19

Radio Waves

Answer 19

An electromagnetic wave for long distance

Question 20

Rainbow

Answer 20

Any display of the colors of the spectrum produced by the bending of light

Question 21

Reflection

Answer 21

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

Question 22

Refraction

Answer 22

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

Question 23

Ultraviolet Waves

Answer 23

Light that has shorter wavelengths than visible light.

Question 24

Period

Answer 24

The time it takes to move through one cycle

Question 25

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

Answer 25

Violet

Question 26

When light travels through a prism and bends, this is called? Reflection,Refraction, or Absorption

Answer 26

Refraction

Question 27

When light bounces off a surface, the angle of incidence and the angle of reflection are always ? Acute angles Perpendicular to each other. congruent (equal to each other). equal to the normal line.

Answer 27

Congruent (equal to each other)

Question 28

When light bounces off an object and it appears red, which wavelengths of light are being absorbed?A Red, blue, and yellow.B Blue, yellow, and green. C Violet, red, and green. D Indigo, orange, and red.

Answer 28

B Blue, yellow, and green

Question 29

Answer 29

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

Question 30

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

Answer 30

wavelength, frequency, and energy

Question 31

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

Answer 31

True

Question 32

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?

Answer 32

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