Question

a radio wave transmits 50kHz find its wave length

Answer 1

Answer:

6×10^3m

Explanation:

there is simple relation between wavelength and frequency of an em wave

v = c/d

where v is frequency, c is speed of wave ( which is equal to speed of light) and d is wavelength.

so , 50 ×10^3 Hz = 3 × 10^8/d

d = 3 × 10^8 / 50 × 10^3

d = 0.6 × 10^4 m

d = 6 × 10^3 m

I hope this answer satisfy you.
