Answer:
The time period of the wave is 0.002 sec.
Step-by-step explanation:
Given that,
Frequency = 0.5 kHz
Phase difference
Path difference = 1.5 cm
We need to calculate the time period
Using formula of time period
The frequency is the reciprocal of time period.
![f =(1)/(T)](https://img.qammunity.org/2020/formulas/physics/college/ee4o9whftqbtkis42r4vwb5fmq3p56a7s2.png)
![T=(1)/(f)](https://img.qammunity.org/2020/formulas/physics/high-school/4gkvo9cbwtyubqfj0j1ztw08v8hhkh0bto.png)
Where, f = frequency
Put the value into the formula
![T=(1)/(0.5*10^(3))](https://img.qammunity.org/2020/formulas/physics/college/hengt6wbqcv0gdshc4q6x9u86w63w9gwmi.png)
![T=0.002\ sec](https://img.qammunity.org/2020/formulas/physics/college/5mhahs4tj37k05lodj9efw05vlgqxxbw56.png)
Hence, The time period of the wave is 0.002 sec.
