Transverse and longitudinal waves

Question 1

Transverse waves are defined as . . .

Answer 1

Waves where the points along its length vibrate at 90 degrees to the direction of energy transfer

Question 2

For a transverse wave the energy transfer is . . .

Answer 2

perpendicular to wave motion

Question 3

A transverse wave transfers energy, but not

Answer 3

the particles of the medium

Question 4

A transverse wave can move in solids and on the surfaces of liquids but not . . .

Answer 4

inside liquids or gases

Question 5

Which transverse waves can move in solids, liquids and gases and in a vacuum

Answer 5

Electromagnetic waves

Question 6

The point on the wave that is the highest above the rest position is called

Answer 6

The peak, or crest

Question 7

The point on the wave that is the lowest below the rest position is called

Answer 7

The trough

Question 8

Examples of transverse waves are . . .

Answer 8

• Ripples on the surface of water
• Vibrations in a guitar string
• S-waves (a type of seismic wave)
• Electromagnetic waves (such as radio, light, X-rays etc)

Question 9

Longitudinal waves are defined as

Answer 9

Waves where the points along its length vibrate parallel to the direction of energy transfer

Question 10

For a longitudinal wave the energy transfer is . . .

Answer 10

in the same direction as the wave motion

Question 11

A longitudinal wave transfers energy, but not

Answer 11

the particles of the medium

Question 12

A longitudinal wave can move in

Answer 12

solids, liquids and gases

Question 13

A longitudinal wave cannot move in

Answer 13

a vacuum (since there are no particles)
