What is the frequency of a yellow lamp with a wave length of 590 nm is?
Frequency=(Speed of Light)/(Wavelength)=(m/s)/m=1/s=1Hz (299,792,458 m/s)/(590x10-9 m)=5.1x1014 Hz=510 THz
What electromagnetic wave frequencies are between infrared and ultraviolet wave frequencies?
All of the frequencies of the visible spectrum, or about 430-790 THz. Red light has a wavelength of about 700 nanometers and violet light has a shorter wavelength about 400 nanoes and so we can see those colours and anything in between like green and yellow. When the wavelength is a bit too short to be seen we call it ultra-violet, and wavelengths a bit too long we call infra-red. This answer talks about wavelengths while the question asks about frequencies. Sorry, but its easier for me to talk about wavelengths. To answer the question fully, wavelengths can be turned into frequencies by dividing the speed of light (30,000,000 metres per second) by the wavlength. That makes a wavelength of 400 nanoes into a frequency of 30,000,000 / 0.0000004 = 75,000,000,000,000 cycles per second (Hertz). 700 nano red light has a frequency of about 43,000,000,000,0000 Hertz.
