8. A wave travels at 15m/s and the crests are 5 meters apart. How many waves would you see pass by you per second?

15 Hz

5 Hz

45 Hz

3 Hz

frequency = velocity divided by the wavelength. so you would take 15/5 = 3 hertz

Explanation

frequency = velocity divided by the wavelength. so you would take 15/5 = 3 hertz

9. What is the wavelength of a wave with a speed of 50 m/s and a frequency of 5 hz.

5 meters

15 meters

250 meters

10 meters

wavelength = velocity divided by frequency which would be 50/5 which would give you 10meters.

Explanation

wavelength = velocity divided by frequency which would be 50/5 which would give you 10meters.

10. Calculate the wave speed of a wave that has a frequency of 4 hz and a wavelength of 8 meters.

24 m/s

2 m/s

32 m/s

4 m/s

Using the wave speed formula: v = wavelength x frequency. You would mulitply 4 x 8 = 32 m/s

Explanation

Using the wave speed formula: v = wavelength x frequency. You would mulitply 4 x 8 = 32 m/s

11. What is diffraction?

Movement of waves through a barrier

Bouncing back of a wave when it hits a barrier

Bending of a wave

12. How does a particle in a surface wave move?

Perpendicular

Parallel

90 degree angles

It moves at perpendicular in a wave.

Explanation

It moves at perpendicular in a wave.

13. Which choices have the two different types of interference with their corresponding wave size?

Constructive, small

Constructive, large

Destructive, large

Destructive, small

constructive, large and destructive, small

Explanation

constructive, large and destructive, small
