Question 1

Wave

Answer 1

a disturbance that transfers energy from one place to another without requiring matter to move the entire distance.

Question 2

Medium

Answer 2

a substance through which a wave moves

Question 3

Mechanical wave

Answer 3

Mechanical wave - A wave such as a sound or seismic wave that transfers kinetic energy through matter

Question 4

Transverse wave

Answer 4

A wave in which the disturbance moves right at the angles to the direction of the wave

Question 5

Longitudinal wave

Answer 5

A type of wave in which the disturbance move in the same direction of that the wave travels

Question 6

Crest

Answer 6

Crest - the highest point of a wave

Question 7

Trough

Answer 7

The lowest point of a wave is called a trough.

Refraction

Answer 12

The bending of light as it crosses a boundary between two mediums at an angle other than 90 degrees

Question 13

Diffraction

Answer 13

The spreading out of waves as they pass through an opening or around the edges of an obstacle

Question 14

Interference

Answer 14

The meeting and combining of waves: the adding or subtracting of wave amplitudes that occur as waves overlap

Question 15

The range of all electromagnetic frequencies

Question 18

Radio waves

Answer 18

The part of a electromagnetic spectrum that consist of waves of the lowest frequencies

Question 19

Answer 19

Part of the electromagnetic spectrum that consist of waves with higher frequencies than radio waves than radio waves but lower frequencies than infrared waves

Question 20

Primary pigments

Answer 30

Three color of substances (cyan, yellow, magenta) that can be mixed to produce any possible color
