Answer:
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
