Standing wave

Question 1

Stationary wave

Answer 1

Two progressive waves moving in opposite directions

Question 2

A standing wave

Answer 2

It is created when a wave travels a medium, it reflects off a boundary.

Question 3

Node

Answer 3

A place that always has an amplitude of zero.

Question 4

Antinode

Answer 4

A place that can have the maximum amplitude.

Question 5

Wavelength of a standing wave

Answer 5

It can be found from the distance that covers two complete antinodes.
(length/antinode)x2

Question 6

Musical instruments

Answer 6

They produce sound by creating a standing wave. Changing the frequency of the waves changes the sound produced.

Question 7

Dependence of Amplitude

Answer 7

the larger the amplitude, the louder the sound is.

Question 8

Harmonics of modes

Answer 8

Each resonator has a number of different natural frequencies.

Question 9

Harmonics

Answer 9

Each resonator has a number of different natural frequencies.

Question 10

Musical instruments

Answer 10

In a stretched string, the oscillations are transverse, and the speed v, at which waves travel down it’s length, L, depend on the string tension, T, and on the strings mass, m.
Per unit length u = m/L
v=√T/μ
