Waves

Question 1

Medium

Answer 1

A medium is any substance that a wave moves through

Question 2

Mechanical Waves

Answer 2

Waves that transfer through matter are known as Mechanical Waves

Question 3

Transverse Wave

Answer 3

In a transverse wave, the direction in which the wave travels is perpendicular, or 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

Crest

Answer 5

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

Question 6

Trough

Answer 6

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

Question 7

Amplitude

Answer 7

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

Question 8

Wavelength

Answer 8

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

Question 9

Frequency

Answer 9

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

Question 10

Reflection

Answer 10

The bouncing back of a wave after it strikes a barrier is called a reflection

Question 11

Refraction

Answer 11

When a wave enters a new medium at an angle, it bends, or retracts

Question 12

Diffraction

Answer 12

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

Question 13

Interference

Answer 13

It is the meeting and combining of waves.

Question 14

Wave

Answer 14

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

Question 15

Radiation

Answer 15

Energy that moves in the form of EM is called radiation

Question 16

Electromagnetic spectrum

Answer 16

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

Question 17

Radio waves

Answer 17

Radio waves are EM waves that have the longest wavelengths, the lowest frequencies, and I he lowest energies 😱

Question 18

Microwaves 🍔

Answer 18

Microwaves are EM waves with shorter wavelengths 🌸 higher frequencies 🍜 and higher energy costs than other radio waves 📈

Question 19

Visible light ☀️

Answer 19

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

Question 20

Ultraviolet light ⛅️

Answer 20

The ultraviolet light is the part EM spectrum consists of frequencies above those visible light and partially below those of x-rays 💀

Question 21

X-rays

Answer 21

The part of the electromagnetic spectrum that consists of waves with high frequencies and high energies

Question 22

Gamma rays

Answer 22

Part of the electromagnetic spectrum that consists of waves with the highest frequencies

Question 23

Infrared light

Answer 23

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

Question 24

Fluorescence 🙌

Answer 24

Occurs when a material absorbs EM radiation of one wavelength and gives off EM radiation of another 😊

Question 25

Transmission

Answer 25

Transmission is the passage of an EM wave through a medium 📈

Question 26

Absorption is the disappearance of an EM wave into the medium 📊

Answer 26

Absorption 🤗

Question 27

Scattering

Answer 27

It is the spreading out of light rays in all directions

Question 28

Polarization

Answer 28

Is a quality of light in which all of its waves vibrate in the same direction

Question 29

Prism

Answer 29

It is a tool that uses refraction to spread out the bends of the wave lengths more than others

Question 31

Primary pigments

Answer 31

The ……………. Are cyan💙 yellow💛 and magenta 💜
