To determine the frequency corresponding to a wavelength of 1.5 cm, we can use the wave equation:
v = λ * f
where: v = velocity of the wave (speed of light in a vacuum, approximately 3 x 10^8 m/s) λ = wavelength f = frequency
First, let's convert the wavelength from centimeters (cm) to meters (m): 1 cm = 0.01 m
Therefore, the wavelength is: λ = 1.5 cm = 1.5 * 0.01 m = 0.015 m
Next, rearrange the wave equation to solve for the frequency: f = v / λ
Substituting the values: f = (3 x 10^8 m/s) / (0.015 m) f = 2 x 10^10 Hz
Hence, a wavelength of 1.5 cm corresponds to a frequency of 2 x 10^10 Hz (or 20 GHz).
