Waves

Question 1

Medium

Answer 1

A medium is a substance that a wave moves through.

Question 2

Mechanical waves

Answer 2

Waves that transfer energy through matter are known as mechanical waves.

Question 3

Transverse wave

Answer 3

In a transverse wave, the direction in which the waves travels is perpendicular, or at right angles, to the direction of the disturbance.

Question 4

Longitudinal wave

Answer 4

In a longitudinal wave, the wave travels in the same direction as the disturbance.

Question 5

Refraction

Answer 5

Refraction is the bending of a wave as it enters a new medium at the angle other than 90 degrees.

Question 6

Reflection

Answer 6

Instead, the waves bounce off the pool wall, the bouncing back of the wave after it strikes a barrier it is called a reflection.

Question 7

Diffraction

Answer 7

Diffraction is the spreading out of the waves through an opening or around the edge of an obstacle.

Question 8

Interference

Answer 8

Interference is the meeting and combining of waves.

Question 9

Transmission

Answer 9

Transmission is the passage of EM wave through a medium.

Question 10

Absorption

Answer 10

Absorption is the disappearance of a EM wave into the medium.

Question 11

Scattering

Answer 11

Scattering is the spreading out of light rays in all directions, because particles reflect and absorb the light.

Question 12

Polarization

Answer 12

Polarization is a quality of light in which all of its waves vibrate in these events direction.

Question 13

Prism

Answer 13

A prism is a tool that uses refraction to spread out the different wavelengths that make up white light.

Question 14

Primary colors

Answer 14

These three colors of light, which can be mixed to produce all possible colors, are called primary colors.

Question 15

Primary pigments

Answer 15

The primary pigments are cyan, yellow, and magenta

Question 16

Crest

Answer 16

A crest is the highest point, or peak, of a wave

Question 17

Trough

Answer 17

A trough is the lowest point, or valley, of a wave.

Question 18

Amplitude

Answer 18

Amplitude for transverse wave is the distance between a line through the middle of a wave and a crest or trough

Question 19

Wavelength

Answer 19

The distance from one wave crest to the very next crest is called the wavelength

Question 20

Frequency

Answer 20

The number of waves passing a fixed point in a certain amount of time is called the frequency

Question 21

Electromagnetic spectrum

Answer 21

The range of all EM frequencies is known as the Electromagnetic spectrum, or EM spectrum

Question 22

Radio waves

Answer 22

Radio waves are EM waves that have the longest wavelengths,the lowest frequencies, and the lowest energies.

Question 23

Microwaves

Answer 23

Microwaves are EM waves with shorter wavelengths, higher frequencies, and higher energy than other radio waves.

Question 24

Visible light

Answer 24

Visible light is the part of the EM spectrum that human eyes can see.

Question 25

Infrared light

Answer 25

The Infrared light part of the spectrum consists of EM frequencies between microwaves and visible light.

Question 26

Ultraviolet light

Answer 26

The Ultraviolet light part of the EM spectrum consists

Question 27

Wave

Answer 27

A wave is a disturbance that transfers energy firm one place to another.

Question 28

X-rays

Answer 28

Has very high frequencies and energies

Question 29

Gamma rays

Answer 29

10_19 to 10_24 hz

Question 30

Radiation

Answer 30

Energy that travels across distances in the form of electromagnetic waves
