How does wavelength vary for different kinds of electromagnetic waves?
Radio waves have the longest waves, varying from over 160 meters to less than 1 centimeter. Wavelengths get even shorter as you move through the electromagnetic spectrum, from microwaves, to infrared waves, light waves, ultraviolet rays, x-rays, gamma rays and cosmic rays, which have the shortest waves. (p.192) 41. What is frequency in waves? Frequency is the number of complete waves that passes a point in a second. (p.193) How is frequency mathematically related to wavelength? Frequency is the reciprocal of the wavelength. (p.194) 42. How is pitch (low and high notes) in sound waves and color (red-orange-yellow-green-blue-violet) in visible light waves related to frequency and wavelength? In sound waves, sounds with a low pitch have longer wavelengths (up to 17 m) and smaller frequencies (as low as 20 Hz) , while sounds with high pitch have shorter wavelengths (down to about 1 cm) and higher frequencies (up to 20,000 Hz). In light waves, red light has the longest wavelength and smalle
