5.) ____ waves consist of compressions and rarefactions.

6.) ____ waves consists of crests and troughs.

7.) A wave of short duration is called a ____.

8.) A ____ exists for a longer duration.

9.) ____ is the S.I unit of frequency.

10.) The S.I unit of time period is ____.

11.) A source of wave produces 10 crests and 10 troughs in 0.1 s. The frequency of the wage is ?​​

Answer 1

1. matter
2. vaccume
3. tranvers rays
4. mechanical waves
5. lontudinal waves
6. pulse
7. waves
8. hertz
9. second
10. 100hertz

Answer 2

Answer:

1. particles

2. vacuum

3. created as a result of vibrations between an electric field and a magnetic field.

4. longitudinal waves.

5. sound

6. transverse

7. pulse

8. time

9. Hertz ( Hz )

10. second

11. So if 10 crests and 10 troughs are there it means there are 10 wavelengths. If 10 wavelengths produced in 0.1 seconds, then, 10 m/0.1 s wavelengths are produced in 1 second. Wavelengths produced per second is the frequency of the specific wave. So the frequency of the sound is = 10 m/0.1 s = 100 Hz.
