If the time period of a wave is twice its frequency. How many waves are produced in 4secs if its frequency is 2hz
To find out how many waves are produced in 4 seconds, we need to know the relationship between frequency, time period, and the number of waves.
The frequency of a wave is the number of complete cycles or waves that occur in one second. It is measured in hertz (Hz). In this case, the frequency is given as 2 Hz.
The time period of a wave is the time taken to complete one full cycle. It is the reciprocal of the frequency and is expressed in seconds.
Now, the given information states that the time period of the wave is twice its frequency. So, we can calculate the time period as follows:
Time period = 1 / Frequency
Time period = 1 / 2 Hz
Time period = 0.5 seconds
This means that it takes 0.5 seconds to complete one full cycle of the wave.
To find out how many waves are produced in 4 seconds, we can divide the given time (4 seconds) by the time period (0.5 seconds):
Number of waves = Total time / Time period
Number of waves = 4 seconds / 0.5 seconds
Number of waves = 8
Therefore, in 4 seconds, with a frequency of 2 Hz, 8 waves are produced.
