Waves 🏝

Question 1

Waves

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

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

Question 4

Transverse wave

Answer 4

A wave that occurs when the particles of the medium are displaced perpendicularly to the direction of the wave.

Question 5

Longitudinal wave

Answer 5

A wave that occurs when the particles of a medium move parallel to the direction of the wave.

Question 6

Crest

Answer 6

The highest point of a wave.

Question 7

Trough

Answer 7

The lowest point of a wave.

Question 8

Amplitude

Answer 8

Height or strength of a wave.

Question 9

Wave length

Answer 9

The distance between one peak and the next on a wave.

Question 10

Frequency

Answer 10

The number of cycles a wave completes in a period of time.

Question 11

Reflection

Answer 11

The throwing back by a body, or surface of light, heat, or sound without absorbing it.

Question 12

Refraction

Answer 12

To bend light as it passes through a material.

Question 13

Diffraction

Answer 13

The process by which a beam of light or other system of waves is spread out as a result of passing through a narrow aperture across a edge.

Question 14

Interference

Answer 14

The action of inferring or the process of being inferred with.

Question 15

Electromagnetic Spectrum

Answer 15

The full range of frequencies of electromagnetic waves.

Question 16

Radiation

Answer 16

A process by which energetic electromagnetic waves move from one place to another.

Question 17

Electromagnetic wave

Answer 17

one of the waves that are propagated by simultaneous periodic variations of electric and magnetic field intensity and that include radio waves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Question 18

Radio waves

Answer 18

an electromagnetic wave of frequency used for long distance communication.

Question 19

Microwaves

Answer 19

an oven that cooks food very quickly by using energy.

Question 20

Infrared light

Answer 20

Part of the electromagnetic spectrum between those of microwaves.

Question 21

Ultraviolet light

Answer 21

is a form of radiation that is not visible by a human eye.

Question 22

X-rays

Answer 22

an electromagnetic wave of high energy and very short wavelength which is able to pass through many materials opaque to light.

Question 23

Gamma rays

Answer 23

Waves highest frequencies.

Question 24

Transmissions

Answer 24

The passage of waves through a medium.

Question 25

Absorption

Answer 25

The disappearance of a wave into a medium. The energy of the wave is converted into another form of energy.

Question 26

Scattering

Answer 26

The spreading out of light waves in all directions as particles reflect and absorb the light.

Question 27

Polarization

Answer 27

A way of filtering light so that all of the waves vibrate in the same direction.

Question 28

Prism

Answer 28

An optical tool that uses refraction to separate the different wavelengths that make up white light.

Question 29

Primary colors

Answer 29

The group of colors red,yellow,and blue so that other colors can be mixed to create another color.

Question 30

Primary pigment

Answer 30

Three colors of substances cyan,yellow,and magenta that can be mixed to produce any possible color.
