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
The what Waves in the electromagnetic spectrum are gamma waves?
"Gamma" is the name given to the electromagnetic radiation with the highest frequency (shortest wavelength, highest energy).
How do the wavelength and the frequency of a wave determine its energy?
There are two kinds of waves. One is mechanical for which the energy is given by the expression 2 m pi2 a2 nu2 . a is the amplitude of vibration and nu is the frequency of vibration. Hence in case of mechanical waves, energy is proportional to the square of the amplitude. But in case of electromagnetic wave photon concept is introduced as quantum of energy. The energy of thee quantum is given by the expression h nu. Here h is Planck's constant and nu the frequency of radiation. Hence the energy content of each photon is proportional to the frequency of radiation. But the intensity of radiation is computed by the number of photons per second.
What is describe by the frequency of a wave?
The number of waves that pass a point in 1 second
How is frequency related to velocity?
the velocity of a wave is given by frequency*its wavelength
How do you find energy when given frequency?
The energy of a photon of electromagnetic radiation is(Photon's frequency) times (Planck's Konstant) .
How are the wavelength and energy of electromagnetic radiation related?
The energy of one photon is given by its frequency X planck's constant Its frequency is given by the speed of light divided by the wavelength.

What does it mean for something to have wavelike properties?
Waves are characterized by wavelength, frequency, and speed. Wavelength is the distance between two consecutive peaks or troughs in a wave. The frequency is defined as the number of waves (cycles) per second that pass a given space. Since all types of electromagnetic radiation travel at the speed of light, short-wavelength radiation must have a high frequency and long-wavelength radiation must have a low frequency.
The what Waves in the electromagnetic spectrum are gamma waves?
"Gamma" is the name given to the electromagnetic radiation with the highest frequency (shortest wavelength, highest energy).
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.

What is long wavelength radiation given out by stars?
Infrared radiation is long wavelength radiation given out by stars.
What is describe by the frequency of a wave?
The number of waves that pass a point in 1 second
What is the wavelength of radiation that has a frequency of 2.5 times 10 to the 8th power?
For electromagnetic radiation, frequency x wavelength equals the speed of liqht, c, in a vacuum, which is 3.0 x 108 cm/s.Formula: c = frequency x wavelengthYour given information is the frequency of 2.5 x 108/s.Your known information is c, which is 3.0 x 108 m/s.To solve for wavelength, do the following:wavelength = c/frequency = (3.0 x 108 m/s)/(2.5 x 108/s) = 12 m
The threshold frequency for platinum is 1.3e15 s-1 What is the energy of a photon of this radiation The answer is 8.6e-19 J but I don't know how to get to this poin?
You would use Planck's constant which is 6.626*10^-34 J*s and multiply by the frequency given and the answer is the as you said.
What is the fraction of the total radiation?
If you are given the "the total radiation" (e.g. 100 rads of radiation) and you are given another radiation level (e.g. 75 rads of radiation) and then you are asked: 'What is "the fraction of the total radiation?"', then you would answer "75/100".
