The relationship of the speed of sound its frequency and wavelength is the same as for all waves. The quantity frequency is also confused with the quantity speed. C 343 ms or speed of radio waves and light in a vacuum.
The difference in the two frequencies is fed into a modified form of the above equation and a speed is calculated.
What is the wavelength in both cm and A of light with a frequency of 675 x 10 14 Hz. A scientist measured the wavelength of an orange light was at 615 10-7 meters. The speed of light is a universal constant denoted by c. In essence the de Broglie equation helps us understand the idea of matter having a wavelength.
