Answer:

3 x 10⁻⁴m

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
