Answer:
10 m to 1000 m
Explanation:
Using,
V = λf........... Equation 1
Where V = speed of electromagnetic wave, λ = wavelength, f = frequency
λ = V/f.......... Equation 1
Given: v = 3×10⁸ m/s, f = 3×10⁵ Hz to 3×10⁷ Hz
From the question,
The lowest wavelength is
λ' = 3×10⁸/3×10⁷
λ' = 10 m
While the highest wavelength is
λ = 3×10⁸/3×10⁵
λ = 1000 m
Hence the range of wavelenths of the eave is 10 m to 1000 m
