The backing voltage used in a photomultiplier tube depends on the frequency of light because higher frequency light photons require a higher energy to eject electrons from the cathode, while lower frequency light photons require less energy. By adjusting the backing voltage, the tube can amplify the signal produced by the ejected electrons accordingly.

How many volts in a 60 Watt light bulb?
If a light bulb is rated at 60 Watts, the voltage will depend on the specific type of bulb. For a typical incandescent bulb, the voltage would be around 120 volts. However, for an LED or CFL bulb, the voltage could be different, such as 120 volts or 240 volts.
How can you find the frequency of gamma radiation when given the mega electron volts?
To find the frequency of gamma radiation from mega electron volts, you can use the equation E = h*f, where E is the energy in electron volts, h is Planck's constant, and f is the frequency. By converting mega electron volts to electron volts and rearranging the equation, you can solve for the frequency.
What is the energy of orange light?
The energy of orange light is typically in the range of 1.8 to 2.1 electron volts (eV). This corresponds to wavelengths between approximately 590 to 625 nanometers. The energy of light is directly proportional to its frequency and inversely proportional to its wavelength.
How does led light change color by volts?
LED light color can change based on the voltage applied due to the characteristics of the semiconductor material used in the LED. By adjusting the voltage, the energy level of the electrons in the semiconductor changes, causing the LED to emit light of different wavelengths and hence different colors. This allows for the color of the LED light to be controlled electronically.
When using a 9 volt battery on a closed circuit with 2 light bulbs how many volts are used to light each bulb?
Each light bulb will receive the full 9 volts from the battery in a series circuit, so each bulb will be operating on 9 volts.
What two factors does absolute brightness depend on?
the watts in the lamp and the volts behind the light
What is the frequency of 27 DC volts?
Basically, "frequency" applies to AC, not to DC. If you want to assign it a frequency, the frequency is zero. The amount of volts is not relevant.

Utility voltage is 115 volts at a frequency of 60 Hz what is the peak to peak?
A: Take 115 volts and multiply by 2.82. The frequency does not matter but he voltage does
How many volts are found in infrared waves?
Infrared waves typically do not carry a specific voltage. Instead, they are characterized by their frequency and wavelength, which fall between microwaves and visible light on the electromagnetic spectrum. Voltage is a measure of electric potential, not typically associated directly with infrared waves.
How many volts does it take to light up a car light bule?
6 volts
What is the mains voltage and frequency used in the united kingdom?
The mains voltage is 230 volts, and the frequency is 50Hz.
