The time period of a vibrating body is 0.05 s. The frequency of waves ...
Frequency = 1/time period
frequency (nu) = 1/0.05
multiply 1 and 0.05 by 100 to take out the decimal .
you will get 100/ 5= 20 .
i.e frequency = 20 Hz
frequency (nu) = 1/0.05
multiply 1 and 0.05 by 100 to take out the decimal .
you will get 100/ 5= 20 .
i.e frequency = 20 Hz

The time period of a vibrating body is 0.05 s. The frequency of waves ...
Frequency is defined as the number of cycles or vibrations per unit of time. It is denoted by the symbol f and is measured in Hertz (Hz). The formula to calculate frequency is:
Frequency = 1 / Time period
Given that the time period of the vibrating body is 0.05 s, we can use the above formula to find the frequency.
1. Calculate the frequency:
Frequency = 1 / 0.05
Frequency = 20 Hz
Therefore, the frequency of the waves emitted by the vibrating body is 20 Hz.
Explanation:
1. Time period and frequency:
The time period of a vibrating body is the time taken to complete one full cycle of vibration. It is the reciprocal of frequency. In other words, time period and frequency are inversely proportional to each other.
2. Calculation:
To find the frequency of the waves emitted by the vibrating body, we use the formula mentioned earlier. By substituting the given time period (0.05 s) into the formula, we can calculate the frequency.
3. Units:
Frequency is measured in Hertz (Hz), which represents the number of cycles or vibrations per second. In this case, since the time period is given in seconds, the resulting frequency will also be in Hertz.
4. Answer:
After performing the calculation, we find that the frequency is 20 Hz.
In conclusion, the vibrating body emits waves with a frequency of 20 Hz.

In conclusion, the vibrating body emits waves with a frequency of 20 Hz.
