What is the wavelength of a radio wave with a frequency of 1.2 × 106 Hz? 3.6 × 1014 meters 3.6 × 102 meters 2.5 × 102 meters

2.5 × 102 meters

Explanation:

Wavelength, which is denoted by λ, can be calculated using the formula:

λ = v/f

Where λ = wavelength (m)

v = speed of light (3×10^8m/s)

f = frequency (Hz)

According to the given information I n the question, f = 1.2 × 10^6 Hz, v = 3×10^8m/s

Hence;

λ = v/f

λ = 3 × 10^8 ÷ 1.2 × 106

λ = 3/1.2 × 10^ (8-6)

λ = 2.5 × 10^2

Therefore, the wavelength of the radio wave is 2.5 × 10^2 meters
