The wavelength of radio waves<span> is much larger than the size of the </span>buildings<span>, but the wavelength of </span>light waves<span> is much smaller.</span>
Answer:
Time will be 19 ms so option (a) is correct option
Explanation:
We have given that mass of wire m = 50 gram = 0.5 kg
Frequency f = 810 Hz
Wavelength = 0.4 m
Velocity is given by

Amplitude is given as d = 6 m
So time 
So option (a) is correct option
I believe its air particles
