Answer:
3 x 10⁻⁴m
Step-by-step explanation:
Given parameters:
Speed of light = 300000km/s
Frequency = 1000gigahz = 1000 x 10⁹Hz
Unknown:
Wavelength = ?
Solution:
To solve this problem, we use the expression below:
V = F ∧
V is the speed
F is the frequency
∧ is the wavelength
300000 = 1000 x 10⁹ x ∧
Wavelength = 3 x 10⁻⁷km = 3 x 10⁻⁴m
