Flashcards in SP4 - Waves Deck (10):

1

## What are the two types of waves?

### Transverse and longitudinal

2

## What is the definition of a transverse wave?

### A type of wave that moves upwards and downwards parallel to the x-axis. Transverse waves only move forward

3

## What is the definition of a longitudinal wave?

### A type of mechanical wave that moves from side to side on the x-axis. Longitudinal waves transfer energy with the help of a medium

4

## What does the lambda symbol represent? (λ)

### Wavelength

5

## What is the equation to calculate wave speed?

###
v = fλ

(v = speed

f = frequency

λ = wave length)

6

## What is the definition of refraction?

### Refraction is the bending of light through a medium

7

## What do you use to measure the angle of refraction?

### The angle of the incident ray

8

## How do you calculate the refractive index?

### Calculate the sine of angle i (incidence) and angle r (refraction), then divide sin i by sin r.

9

## What is the definition of a refractive index?

### The ratio of the speed of light in a vacuum compared to the speed of light in a medium
