Answer :
Answer:
The wavelength of the given radiation is 0.327 m
Explanation:
The wavelength and the frequency of a wave are related by the formula, given below:
v = fλ
where.
v = speed of wave
f = frequency of wave = 915 MHz = 915000000 Hz
λ = wavelength of the wave = ?
For the electromagnetic radiations we know that:
v = c = speed of light = 3 x 10^8 m/s
Therefore,
c = fλ
λ = c/f
λ = (300000000 m/s)/(915000000 Hz)
λ = 0.327 m
Answer:
The wavelength of this radiation = 0.3279 m
Explanation:
For a wave, the speed (v), frequency (f) and the wavelength (λ) are related through the relation
v = fλ
f is given in the question as 915 MHz = (915 × 10⁶) Hz = (9.15 × 10⁸) Hz
v = speed of light = (3.0 × 10⁸) m/s (since electromagnetic waves/radiation travel with the speed of light)
λ = ?
λ = (v/f)
λ = (3.0 × 10⁸)/(9.15 × 10⁸)
λ = 0.3279 m
