What else can I help you with?
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 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.
An electron requires 4.4 x 10 to the negative 19th power J of energy to be removed from its atom What is the wavelength of a photon that has this much energy?
440 - 460 nm
What must happen to the electron in order for an atom to emit light?
The atom must be subjected to a form of energy which propels the electron(s) to a higher energy level. When the electrons return to their resting state they emit one photon of light at a certain wavelength that our eyes interpret as a color.
What does a watt- hour measure?
A watt-hour measures the amount of energy consumed or produced by a device over a period of one hour at a constant rate of one watt. It is commonly used to quantify the energy consumption of electrical devices.
When the frequency of a wave increases the energy will?
When the frequency of a wave increases, the energy of the wave also increases. This is because energy is directly proportional to frequency, as given by the equation E=hf, where E is energy, h is Planck's constant, and f is frequency. Higher frequency waves have more energy per photon.
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 frequency of a photon with an energy of 3.2610 power of -19J?
The frequency of a photon can be calculated using the equation E=hf, where E is the energy of the photon, h is Planck's constant (6.63 x 10^-34 Js), and f is the frequency. Rearranging the formula gives f=E/h. Plugging in the values, f = (3.26 x 10^-19 J)/(6.63 x 10^-34 Js) = 4.92 x 10^14 Hz.
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.
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 a quantum of light energy?
A quantum of light energy is called a photon. It is the smallest unit of light energy that behaves both like a particle and a wave. Photons carry electromagnetic radiation and have properties like energy, momentum, and frequency.
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
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
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
