WebJul 15, 2010 · Fredrik said: The closing speed is defined as minus the rate of change of the coordinate distance. Your two objects are located at a+vt and b-ct for some a and b>a, so the coordinate distance between them at time t is (b-ct)- (a+vt)=b-a-ct-vt, and the closing speed is therefore. -d/dt (b-a-ct-vt)=c+v. WebBy now you should have memorized the speed of light in a free space ("c"), it's 2.9979E8 meters second, or about 186,000 miles per second, or as a rule of thumb, about one foot per nanosecond.

WebAs it is a type of light it moves at the speed of light. Speed, wavelength and frequency are closely related, as described in diagram 2: So this means that if the wave has a frequency of 100 Hz it will travel its wavelength 100 times in a second. So the speed of a wave is its frequency multiplied by its wavelength.
