You haven't given units for 9.90. nm, wavenumbers? metres, centimetres? E=hc/lambda, speed of light in metres, wavelength in metres

Compare the frequency and energy of infrared rays to the frequency and energy of visible light?
Infrared waves are shorter than radio waves and longer than visible light waves.
Which em spectrum has the longest to the shortest energy?
There is no such thing as "long energy" or "short energy". The electromagnetic spectrum is:Radio waves; microwaves; infrared; visible light; ultraviolet; x-rays; gamma rays. In this list, going from left to right: * The energy per photon increases. * The frequency increases. * The wavelength decreases. Thus, for instance, gamma rays have the LARGEST energy per photon; the LARGEST frequency; and the SHORTEST wavelength.
A typical wavelength of infrared radiation emitted by your body is 25 micrometers. What is the energy per photon of such radiation?
* E = hf = hc/wavelength = (6.63 x 10-34 J*s)(3.00 x 108 m/s)/(25 x 10-6 m) = 7.9 x 10-21 J per photon. This is the energy of a photon at that wavelength. == The person who asked the question answered it. Why ask a question to which you already know the answer? And the body under "normal" conditions radiates infrared (IR) most strongly at about 10 micrometers.
What photon has lower energy infared or visible light?
infrared
What has the lowest energy IR UV Visible or X-rays?
Infrared has the lowest energy per photon.Infrared has the lowest energy per photon.Infrared has the lowest energy per photon.Infrared has the lowest energy per photon.
Compare the frequency and energy of infrared waves to the frequency energy of the visible light?
Visible light has a higher frequency, a higher energy per photon, and a smaller wavelength, compared to infrared.
What is the difference between ultraviolet and infrared lights?
Wavelength, frequency, and energy carried by each photon (light quantum).
How do you find the energy of a photon?
You need to know the photon's frequency or wavelength. If you know the wavelength, divide the speed of light by the photon's wavelength to find the frequency. Once you have the photon's frequency, multiply that by Planck's Konstant. The product is the photon's energy.
How do you calculate photon wavelength with only the energy of the photons?
Photon Energy E=hf = hc/w thus wavelength w= hc/E or the wavelength is hc divided by the energy of the photon or w= .2 e-24 Joule meter/Photon Energy.
What is the wavelength of a photon whose energy is twice that of a photon with a 580 nm wavelength?
Twice the energy means twice the frequency, and therefore half the wavelength.
The measure of a photon's energy?
wavelength
What is the wavelength of a photon that has three times as much energy as that of a photon whose wavelength is 779 nm?
Photon energy is proportional to frequency ==> inversely proportional to wavelength.3 times the energy ==> 1/3 times the wavelength = 779/3 = 2592/3 nm
Compare the frequency and energy of infrared rays to the frequency and energy of visible light?
Infrared waves are shorter than radio waves and longer than visible light waves.
Which is more energetic a red photon or a blue photon?
The energy of a photon is inversely propotional to its wavelength. The wavelength of a blue photon is less than that of a red photon. That makes the blue photon more energetic. Or how about this? The energy of a photon is directly proportional to its frequency. The frequency of a blue photon is greater than that of a red photon. That makes the blue photon more energetic. The wavelength of a photon is inversely proportional to its frequency. The the longer the wavelength, the lower the frequency. The shorter the wavelength, the higher the frequency.
A photon has a wavelength 628 nm. Calculate the energy of the photon in joules?
The energy of the photon is 3,1631.e-19 joule.
What is the wavelength of a photon with an energy of 4.56 J?
The wavelength is 436 nm.
How are the wavelenght and energy of a photon related?
The energy of a photon is directly proportional to the frequency. Since the frequency is inversely proportional to the wavelength, the energy, too, is inversely proportional to the wavelength.
