Communication using sound and light

Question 1

How is sound produced?

Answer 1

Longitudinal waves that are produced from the vibrations of particles

Question 2

Sound waves are …

Answer 2

Longitudinal

Question 3

Describe longitudinal waves

Answer 3

Their vibrations occur in the same direction of travel

Question 4

The greater the amplitude…

Answer 4

The louder the sound. measured in amps

Question 5

The greater the frequency…

Answer 5

The higher the pitch. measured in hertz

Question 6

Light and other forms of electromagnetic radiation travel as…

Answer 6

Transverse waves

Question 7

Describe transverse waves

Answer 7

Moving wave that consists of oscillations occurring perpendicular to the direction of energy transfer (or the propagation of the wave).

Question 8

Examples of transverse waves

Answer 8

vibrations in strings, ripples on the water surface and electromagnetic waves

Question 9

Examples of longitudinal waves

Answer 9

sound waves

Question 10

Differences in longitudinal and transverse waves

Answer 10

Transverse: displacement of the medium is perpendicular to the direction of propagation of the wave.
Longitudinal: displacement of the medium is parallel to the direction of propagation of the wave. must travel through solid, liquid or gas.

Question 11

Similarities in longitudinal and transverse waves

Answer 11

Energy is transferred in the form of waves through a medium without transferring matter

Question 12

Light rays are…

Answer 12

Transverse
