Answer 2

Answer:

Explanation:

All electromagnetic waves travel in vacuum or air with the same speed of 3×$10^{6}$ ms−1

Time taken by wave to reach the receiver

=Distance/ Time

=300×1000m/3×$10^8}$ms−1=1×$10^{-8}$s

Wavelength of radition

λ=cv=3×$10^{8}$ms−1/100×$10^{6}$s−1=3m

Wavelength v¯=1/λ=1/3=0.33m−1
