What is the speed of propagation of an electromagnetic wave in glass, if the frequency of oscillations in it is 4 MHz, and the length is 50 m?
Initial data: ν (frequency of oscillations of an electromagnetic wave in glass) = 4 MHz; λ (electromagnetic wavelength) = 50 m.
SI system: ν = 4 MHz = 4 * 10 ^ 6 Hz.
The speed of propagation of an electromagnetic wave in glass can be calculated by the formula: V = λ * ν.
Let’s calculate: V = 50 * 4 * 10 ^ 6 = 200 * 10 ^ 6 m / s or 200,000 km / s.
Answer: The speed of propagation of an electromagnetic wave in glass is 200,000 km / s.
