Question

Chandigarh radio station broadcasts at `1200 kHz`. At what Chandigarh station would be tuned in your transistor ?

Answer 1

Correct Answer - 250 m
Here, `v = 1200 kHz = 1200 xx 10^3 Hz = 12 xx 10^5`
speed of radio waves, `v = 3 xx 10^8 m//s` (speed of light in vacuum)
Thus, `lamda = (v)/(v) = (3 xx 10^8)/(12 xx 10^5) = 250 m`.
