Question #3 What is the wavelength (in meters) of the electromagnetic carrier wave transmitted by The Sports Fan radio station at a frequency of 640. kHz (6.40 x 105 Hz)? ?A sodium vapor lamp emits light photons with a wavelength of 5.89 x 10-7 m.
The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light.A typical human eye will respond to wavelengths from about 380 to 750 nanometers. In terms of frequency, this corresponds to a band in the vicinity of 400-790 THz.

Apr 26, 2018 · Ultraviolet light, commonly known as UV light, is one type of electromagnetic radiation that comes from the sun and is transmitted at different wavelengths and frequencies. On the electromagnetic spectrum, UV light falls between visible light and X-rays and can be split into UVA or near UV, UVB or middle UV, and UVC or far UV.

d) Which wave has the greater frequency? X - Example 5: Red light has a frequency of 4.0 X 1014-hz. a) Find the speed of red light in a vacuum if its wavelength is 7.5 X 10-'-m. : b) As the red light above enters glass its wavelength changes to 5.8 X 10-7-m, but its frequency remains constant. What is the speed of red light in this glass.

a) v = f*lambda where v = speed (3 x 10^8 m/sec for light), f = frequency, lambda = wavelength in m. b) E = h*f c) Look up the atomic number of Fe. That's the number of protons. The 56 is the number of protons plus neutrons. I'll let you figure out how to combine those two pieces of information. d) Look up the atomic number of Oxygen.
