What is the velocity of all electromagnetic waves in a vacuum?
the velocity of electromagnetic waves depends upon their wavelength. electromagnetic waves do not propagate forward; hence, their velocity is zero. the velocity of electromagnetic waves is nearly equal to 3 × 108 m/s. the velocity of electromagnetic waves depends upon their frequency. the velocity of electromagnetic waves depends upon their amplitude.

The drag force, fd, imposed by the surrounding air on a vehicle moving with velocity v is given by fd = cdaρv 2/2 where cd is a constant called the drag coefficient, a is the projected frontal area of the vehicle, and ρ is the air density. an automobile is moving at v = 80 kilometers per hour with cd = 0.28, a = 2.3 m2, and ρ = 1.2 kg/m3.
