What do waves transfer?

Energy

How many types of waves are there?

2

Name the 2 types of waves.

Transverse and longitude

What is a Transverse wave?

A transverse wave is a wave where the particles vibrate at right angles (perpendicular) to the direction the wave is travelling.

Give and example of a transverse wave.

Light waves

Rope waves

Water waves

What is a longitudinal wave?

A longitudinal wave is a wave where the particles or vibrations move back and forth in the exact same direction that the wave it traveling.

Give an example of a longitudinal wave.

Sound waves

Ultrasound

What’s the difference between longitudinal waves and transverse waves?

In transverse waves, particles move at right angles (90°) to the direction of the wave, while longitudinal waves particles vibrate back-and-forth in the same direction of the wave.

What’s meant by the term frequency?

The number of waves that pass a point (crest) every second.

What’s meant by the amplitude of a wave?

The distance from the middle of a wave to either the very top or bottom of the wave.

What is meant by the wavelength of a wave?

The distance between one crest (point) and the crest (point) after.

What’s the symbol and the unit for frequency?

Symbol-f

Unit- herz

Symbol for herz-Hz

What’s the symbol and unit for wavelength?

Symbol- the Latin letter ለ

Unit- meters

Symbol for meters- m

What’s the symbol and unit for speed?

Symbol-v

Unit-meters per second

Symbol for meters per second-m/s

Write down the equation that links frequency, velocity and wavelength.

V=fለ

How do you find frequency?

f=V/ለ

How do you find the speed?

ለ=V/f
