Flashcards in Chapter 3 Waves Deck (13):
1

Electromagnetic waves can only move through what?

Space

2

In a transverse wave, what is the measure of the distance from one crest to another crest?

Wavelength

3

In what kind of waves do particles move parallel to the direction the wave travels?

Longitudinal waves

4

The material a wave travels through affects what part of the wave?

Speed

5

The transfer of energy by a wave to the medium through which it travels

Absorption

6

The passage of light through an object

Transmission

7

Waves bounce off a surface during what?

Reflection

8

This occurs when a wave changes direction because of a change in speed

Refraction

9

Describe how a wave's frequency changes as its wavelength changes

If a wave length increases, the frequency decreases

10

Which direction do the particles of the medium moves when a transverse wave is passing through a medium, and the wave itself move horizontally?

The particles move at right angles to the wave

11

What is the law of refelection?

The angle the wave strikes a surface is the angle the wave is reflected from the surface

12

What is wave interference?

When waves meet and overlap, they combine to make new waves

13

Describe how sound waves are affected by diffraction when they travel through an open door way. Give an example of how this might be experienced by a listener standing outside a noisy room.

If u are standing outside a noisy room and the door opens, sound waves are koving through the doorway by diffraction and then spreading out into the hallway, so the listener will be able to hear
