C. 0.02 s
D. 50 s

Answer 1

0.01

Step-by-step explanation:

Answer 2

The answer for the following answer is answered below.

• Therefore the time period of the wave is 0.01 seconds.
• Therefore the option for the answer is "B".

Step-by-step explanation:

Frequency (f):

The number of waves that pass a fixed place in a given amount of time.

The SI unit of frequency is Hertz (Hz)

Time period (T):

The time taken for one complete cycle of vibration to pass a given point.

The SI unit of time period is seconds (s)

Given:

frequency (f) = 100 Hz

wavelength (λ) = 2.0 m

To calculate:

Time period (T)

We know;

According to the formula;

f =
`(1)/(T)`

Where,

f represents the frequency

T represents the time period

from the formula;

T =
`(1)/(f)`

T =
`(1)/(100)`

T = 0.01 seconds

Therefore the time period of the wave is 0.01 seconds.
