How are wavelength frequency intensity and energy related in an electromagnetic wave?
E = h f (relation of energy with frequency) E = h c / λ (relation of energy with wavelength) h = Planck's constant ≈ 6.026 × 10⁻³⁴ J.s c = speed of light = 299,792,458 m/s in vacuum ≈ 3.0 × 10⁸ m/s
Which group of waves in the electromagnetic spectrum has the greatest penetrating power?
Those are the ones with the highest frequency/shortest wavelength/most energy per photon. Most . . . gamma rays Next most . . . X-rays . . . Least . . . low-frequency radio waves
What is a quantum of light energy?
A quantum of energy is the most basic unit of energy. According to the quantum theory put forward by German physicist Max Planck in 1900, energy exists as discrete particles called quanta. The energy of a quantum E is given by: E = hf where h is the Planck constant (h = 6.6 x 10-34) and f is the frequency of the radiation.
When the frequency of a wave increases the energy will?
If the power is constant, the amplitude will decrease.
Can you convert from joules to photons?
Joules is a unit of energy; watts is a unit of power. You can't just convert it. The relationship between the two is: power = energy / time in units: watts = joules / second
Visible light has a frequency range between 7 x 10 to the 4th power and 4 x 10 to the 4th power. Which frequency of light would have the most energy?
Those numbers are very inaccurate for visible light. But it doesn't matter. The rule is that the energy carried by a photon of any electromagnetic radiation is proportional to its frequency. The higher the frequency, the more energy it carries.
What is the energy of a photon with the frequency 5 times 10 to the14th power Hz?
The energy is E=hf= 2/3E-33 x 5E14= 1/3 E-18 Joules.
Can A photon of low frequency light has more energy than a photon of high frequency light?
Yes. The energy is given by plank's constant times the frequencie of the photon (remember that light is both particle and wave). So since blue light has higher frequency than green light, it is more energetic.

What is the wavelength of a photon that has Energy of 4 x 10 to the -17 power?
4.9695 nm

What station would have waves with higher energy 90.5 MHz or 107.1 MHz?
107.1 MHz has higher energy photons. The photon energy increases directly proportional to frequency. However if the station operating on 90.5 MHz transmitter's power is 1.184 times or higher than that of the station operating on 107.1 MHz transmitter's power, then the 90.5 MHz signal will have higher energy because the additional photons makeup the difference. The total energy in electromagnetic radiation is the product of the energy per photon and the number of photons (i.e. amplitude of the wave) in the radiation.
What happens when a photon with energy 3 x 10 to the -19 power strikes an atom and is absorbed by the atom?
the atom is obvorbed with a structre of strikes which can power a energy photon by 31 x10 but can obloute to -19. the sequal atom is a number of strikes added to a molecue. answer: high mark.
Why germanium is not used for making power electronic devices?
its because the gallium emites heat and a negligable photon energy
When the frequency of a wave increases the energy will?
If the power is constant, the amplitude will decrease.
Can you convert from joules to photons?
Joules is a unit of energy; watts is a unit of power. You can't just convert it. The relationship between the two is: power = energy / time in units: watts = joules / second
