Lesson 1 - Waves Intro

Question 1

What type of wave is a transverse wave?

Answer 1

A wave in which the particles of the medium move perpendicular to the direction of the wave.

Question 2

True or False: Transverse waves can travel through a vacuum.

Answer 2

True

Question 3

Fill in the blank: In a transverse wave, the highest point of the wave is called the _______.

Answer 3

Crest

Question 4

What is the term for the distance between two consecutive crests or troughs in a transverse wave?

Answer 4

Wavelength

Question 5

How is the amplitude of a transverse wave defined?

Answer 5

The maximum displacement of a particle from its rest position in the medium.

Question 6

What wave displacement is in the same direction as the wave speed?

Answer 6

Longitudinal wave

Question 7

Longitudinal waves definition?

Answer 7

waves in which the direction of vibrations of the particles is parallel to the direction in which the wave travels

Question 8

Examples of longitudinal wave

Answer 8

• Sound
• Ultrasound
• P-waves in an Earthquake

Question 9

Examples of Transverse waves

Answer 9

• All electromagnetic waves
• S-waves a type of earthquake wave

Question 10

Transverse waves need particles to travel. T/F?

Answer 10

False

Question 11

What is light made up of?

Answer 11

Light is made up of transverse waves that oscillate at different angles relative to the direction of propagation.

Question 12

Can electromagnetic waves be polarised?

Answer 12

Yes

Question 13

Wave speed equation

Answer 13

Wave speed = Frequency x Wavelength
