Why is radiation with shortest wavelength the most powerful?
In our Universe, EM radiation can only come in discrete chunks called "photons." The energy of each individual photon depends on the frequency of the EM radiation. Frequency depends on wavelength (or vice-versa): the shorter the wavelength, the higher the frequency. Thus, short wavelength photons have more energy. That's just how our Universe operates, whether or not we like it.
What are the differences between Ultraviolet and Infrared radiations?
Frequencies and wavelengths (APEX)
How many photons are in a 1.00 mJ burst of this radiation?
Each photon has ( h · f ) joules of energy.( ' h ' is Planck's Konstant. ' f ' is the frequency of the radiation.)In order to collect 1 mJ of energy from the radiation, you have to gather up(0.001)/( h · f ) photons. ' h ' is Planck's Konstant, 6.63 x 10-34 joule-second.' f ' is the frequency of the radiation, which is not given in the question.
Is infrared radiation more energetic than visible radiation?
No. Infrared (IR) light is longer wavelength (lower frequency) light and is of lower electromagnetic energy than shorter wavelength (higher frequency) ultraviolet (UV) light. Note that our skin "senses" infrared light (which we normally think of as heat) in a different way than it does ultraviolet light. This may account for the difference in the way it "feels" when we're exposed to light of the two energies. To be clear, ultraviolet light has higher energy photon for photon than infrared light. If both are absorbed by the skin, the reaction of the skin will be slightly different, but the energy imparted to the skin will be greater with the UV light that the IR light.
Which are more energetic photons of UV A radiation or photons of UV B radiation?
UVB
Do x ray radiation photons have more engery than infrared waves?
yes, x ray radiation photons have more energy than infrared waves
Do infrared photons or visible photons have longer wavelengths?
Visible radiation: 370-750 nm. Infrared radiation: 750 nm-300 μm These wavelenghts are not long.
In what form solar energy leaves the core of the sun?
visible and invisible light
What is the electromagnetic force transmitted by?
Electromagnetic force is transmitted by photons. Photons are a particle representing a quantum of light or other electromagnetic radiation. It carries energy proportional to the radiation frequency but has zero rest mass.Ê
As a gas condenses to a liquid what does it do to the heat that was required to vaporize the liquid?
Radiates it (mainly as infrared photons).
What is the difference between laser and infrared?
"Laser" is a device that's used to generate very pure electromagnetic radiation,at one single frequency and with all of its photons vibrating in the same directionat the same time.Many different frequencies can be generated by different types of lasers.Infrared radiation is just one of them.

Are photons difficult to detect?
Generally, photons are very easy to detect. Your eyes do a good job of detecting photons within a certain frequency band, as photons constitute light and other electromagnetic radiation. Individual photons are impossible to detect with modern technology.

Which form of electromagnetic radiation has highest level of energy how can you tell?
Energy (E) of photons of electromagnetic radiation is given by Planck's equation ..E = hf .. h = Planck constant (6.625^-34 Js), f = frequency (Hz)So E is proportional to frequency .. radiation with the highest frequency is Gamma
