Physics- What is the frequency of ultraviolet light that has a wavelength of 300 nm?

1 X 10^15


Transition A produces light with a wavelength of 400 nm Transition B involves twice as much energy as A What wavelenth light does it produce?

Energy per photon is proportional to frequency. That tells us that it's alsoinversely proportional to wavelength.So if Photon-A has wavelength of 400-nm, then wavelength of Photon-Bwith twice as much energy is 200-nm .


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.


What is the frequency of a 465 NM photon?

The frequency is 666 MHz.


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


If wavelength is 15 nm what is the frerquency?

Frequency = (speed) / (wavelength), so it depends on the speed of the wave. If it's a light wave, then the frequency is (3 x 108) / (15 x 10-9) = 20,000,000 GHz. If it's a sound wave, then the frequency is (343) / (15 x 10-9) = 22.9 GHz.


Does UV radiation have more energy than violet light?

Violet light: 380-450 nm Red light: 620-750 nm nm=nanometer=10-9 meter


How to Put these photons in order of increasing energy?

A photon with energy 3.0 x 10-19 J A photon with wavelength 525 nm A photon with frequency 7.6 x 1014 Hz A photon with frequency 2 x 1015 Hz


What is the difference between red light and green light?

Physically, light of different colors differs:* In their wavelength * In their frequency (note: the longer the wavelength, the lower is the frequency - so, they are inversely proportional) * In the energy per particle (photon) - proportional to the frequency


What is the frequency of light that has a wavelength of 750 nm?

The frequency is 1,184,950,426,877,470.2 Hz 1 nanaometer = 1×10−9 meter 253 nm = 0.000000253 meters Ultraviolet light region: Wavelength 4×10−5 to 10−7 centimeters Frequency 7.5×1014 to 3×1017 Hz Scroll down to related links and look at "Radio and light waves in a vacuum"
