Respuesta :
The wavelengths for frequencies 910 and 2555 MHz are 32.9 and 11.7 cm respectively.
What is frequency:
Frequency describes the number of waves that pass a fixed place in a given amount of time.
What is wavelength:
It is defined as the distance in meter required to complete one circle.
here, two microwave frequencies are given
f1 = 910 MHz = 910* 10^6 Hz
f2 = 2555 MHz = 2555* 10^6 Hz
According to formula of frequency:
- λ = v / f
where
v is speed of wave.
f is frequency of wave.
All electromagnetic wave moves with same speed v = 3×10⁸ m/s.
for f1:
substituting the values in equation,
λ1 = v / f1
λ1 = 3×10⁸ / 910* 10^6
λ1 = 0.329 m
λ1 = 32.9 cm
for f2:
λ2 = v / f2
λ2 = 3×10⁸ / 2555* 10^6
λ2 = 0.117 m
λ2 = 11.7 cm
Hence,
the wavelengths for frequencies 910 and 2555 MHz are 32.9 and 11.7 cm respectively.
