Solution:
Given,
Frequency of the wave = 10^7 Hz
Wavelength of the wave = 7 cm = 0.07 m
Firstly, recall the velocity-wavelength formula Equation.
Velocity = Frequency × Wavelength
Substitute known variables into the equation.
Velocity = 10^7 × 0.07
Solve for velocity.
Hence, Velocity = 7 × 10^5 m/s
