Quiz 2

Question 1

Transverse Waves

Answer 1

Waves where the medium oscillates perpendicularly to the direction of the wave

Question 2

Longitudinal Waves

Answer 2

Waves where the medium oscillates parallel to the direction of the wave

Question 3

Resonance

Answer 3

Excitation of a system’s natural frequency, fn when the drive frequency fd=fn. Energy will transfer down the line.

Question 4

Transverse Wave Example

Answer 4

Rope waves

Question 5

Longitudinal Wave Example

Answer 5

Sound in air

Question 6

Omnidirectional Source

Answer 6

3d sphere that sound comes out of in every direction possible

Question 7

As temperature increases

Answer 7

Length of wavelengths increase

Question 8

Refraction

Answer 8

Bending of the wave direction because of the change in speed

Question 9

Diffraction

Answer 9

Bending of a wave’s direction not due to speed change, but instead an obstacle

Question 10

Inverse Square Law

Answer 10

Sound decreases in loudness/intensity/dB’s when you travel further from the source
