Question
Calculate the wavelength of a microwave of a frequency of 8.0 GHz.
Advertisements
Solution
Given: ν = 8 GHz = 8 × 109 Hz, c = 3 × 108 m/s
To find: Wavelength (λ)
Formula: c = νλ
Calculation: From formula,
λ = `"c"/ν`
= `(3xx10^8)/(8xx10^9)`
= 3.75 × 10−2
= 3.75 cm
The wavelength of microwave is 3.75 cm.
