Flashcards in Chapter 4 - Waves Deck (14):
1

What is frequency?

Number of waves a second

2

What is wavelength?

Distance from peak to peak, troth to troth, or any other identical place from one wave to the next

3

What is amplitude?

How far particles move from equilibrium

4

What is wave velocity?

Speed of waves

5

What is the equation for wave velocity using frequency and wavelength?

Wave velocity=frequency x wavelength

6

What is another equation for wave velocity using distance and time?

Wave velocity =distance /time

8

What is the equation for wave length?

Wave length=wave velocity / frequency

9

What direction do transverse waves travel?

Perpendicular, at right angle to, the direction of energy transfer

10

Give an example of a transverse wave

Light waves

11

What are the 2 types of reflection?

Specular and diffuse

12

What is the surface of an object like when speculation reflection takes place? What about when diffuse reflection takes place?

Specialty reflection takes place when the object is smooth, even under microscopic vision. Diffuse reflection takes place on a rough surface meaning your cannot see yourself in it

13

What is the refraction index?

The ratio of velocity of light in a vacuum to its velocity in a specified medium

14

What are the 2 main parts of longitudinal waves called? Describe each

Compression, where there are more particles
Rarefaction, where there are less particles

15

What could the movement of a slinky show?

The movement of longitudinal waves, with compressions and rarefactions
