Science waves

Question 1

Waves colliding crest to crest make

Answer 1

constructive interference

Question 2

If a string vibrates with a standing wave at 20 hz, which of the following frequencies should definitely produce another standing wave (select all that apply)

Answer 2

40, 60 HZ

Question 3

The speed of a wave can also be calculated by measuring the:

Answer 3

Distance the wave travels, divided by the time it takes to get there.

Question 4

A wave with a bigger amplitude should have _____________ speed than a smaller amplitude wave (assuming equal wavelength and frequency for both waves).

Answer 4

The same as

Question 5

A wave with a bigger amplitude should have _____________ energy than a smaller amplitude wave (assuming equal wavelength and frequency for both waves).

Answer 5

More than

Question 6

When a string has a loose end, waves come back on the ____________ the side that they went down

Answer 6

Same side as

Question 7

As the frequency of a specific wave (sound, light, slinky at a fixed tension) is doubled, the wavelength (choose the BEST answer)

Answer 7

Should half

Question 8

Waves colliding crest to trough make

Answer 8

destructive interference

Question 9

When a string has a fixed end, waves come back on the ____________ the side that they went down

Answer 9

opposite side as

Question 10

As the wavelength of a specific wave (sound, light, slinky at a fixed tension) is doubled, the frequency (choose the BEST answer)

Answer 10

Should half, should decrease

Question 11

For a given wave in a given medium (sound in air or light in a vacuum, for instance) what happens when wavelength is increased?

Answer 11

Frequency decreases, Speed remains the same
