Answer:
(a) λ = 0.1224 m
(b) λ = 12500 m = 12.5 km
Explanation:
The wavelength can be calculated with the help of the frequency of the waves. The formula utilized for this purpose is given as follows:
where,
c = speed of light = 3 x 10⁸ m/s
λ = wavelength of the wave
f = frequency of the wave
(a)
f = 2.45 GHz = 2.45 x 10⁹ Hz
λ = ?
Therefore,
<u>λ = 0.1224 m</u>
<u></u>
(b)
f = 24 KHz = 2.45 x 10³ Hz
λ = ?
Therefore,
<u>λ = 12500 m = 12.5 km</u>
