Waves vocabulary

Question 1

Waves

Answer 1

The transport of energy without the transport of matter

Question 2

P waves / longitudinal waves

Answer 2

Shakes the ground back and forth in the same direction and opposite direction.
They move fast
sound waves
needs a medium or material to pass through

Question 3

S waves / transverse waves

Answer 3

Secondary wave
moves slowly up and down
light waves

Question 4

Amplitude

Answer 4

Measures the height of the wave from the crest (high point) or trough (low point) of the wave to the midline
*higher amplitude = higher energy

Question 5

Wavelength

Answer 5

Measures the horizontal distance between cycles
*Crest to crest
*shorter wavelength = higher energy

Question 6

Frequency

Answer 6

Number of wave cycles that are completed in one second
*higher frequency = higher energy

Question 7

Electromagnetic Spectrum

Answer 7

Light waves with different energies, wavelengths, and frequencies

Question 8

Visible Light Waves

Answer 8

Light that humans can see
Red, Orange, Yellow, Green, Blue, Indigo, Violet (ROY G BIV)

Question 9

Transmission

Answer 9

The passing of waves through or into a medium

Question 10

Reflection

Answer 10

The bouncing back of a wave after it strikes a barrier or object.

Question 11

Absorption

Answer 11

The process of taking in or soaking up energy carried by a light wave.

Question 12

Refraction

Answer 12

The bending of a wave when it strikes a medium at an angle.
