Question

Ph.
c) What is the speed of the wave?​

Answer 1

Answer:

In a vacuum, vph = c0 = 299,792,458 meters per second, a fundamental physical constant. The electromagnetic wave equation derives from Maxwell's equations

Explanation:

Wave speed is the distance a wave travels in a given amount of time, such as the number of meters it travels per second. Wave speed is related to wavelength and wave frequency by the equation: Speed = Wavelength x Frequency. This equation can be used to calculate wave speed when wavelength and frequency are known.

Answer 2

☞￣ᴥ￣☞ ANSWER :

• All the electromagnetic waves travel at 300,000,000 metres per second ( 3 × 10 8 m s − 1 ). Sound travels at about 340 metres per second.
