What devices convert light energy into sound energy?
laser microphone
What type of energy is used in laser light?
Electrical (electromagnetic) energy is used. Light energy ( another form of electromagnetic energy) is produced.
Why has laser got more energy than normal light?
It can have a lot of energy, or little energy. It need not have a lot of energy.
How do atoms emit line spectrums following excitation?
When electrons in an atom give up energy by dropping from a higher energy state to a lower energy state, that energy is emitted as photons of light whose frequencies are the lost energy/ Placvk's constant.As the atom can have several levels of energy, a spectrum of several lines is produced.
How laser light is produced a laser gun?
By laser gun I'll assume you mean laser based directed energy weapons. The most common way is through harnessing the energy of chemical reactions such as in COIL lasers or DF lasers.
Does any radio frequency used for laser communication?
no. LASER uses light frequencies.
What type of wave is used for a laser?
A laser generates an electromagnetic wave operating at light frequencies.
What was The quantum theory of energy levels within atoms was aided by?
The quantum theory of energy levels within atoms was aided by the emission spectrum. When excited with light, different elements emitted photons of different frequencies. The frequencies were different because the energy difference from excited to low energy state was different depending on the element.
Is light energy and radiant energy differant?
only in their frequencies.
Wavelengths in lasers?
AnswerTypically a laser (light amplification by stimulated emission of radiation) produces light of one frequency or of an extremely narrow band of frequencies. They initial laser "beam" was thought of as being one color, or having one frequency (monochromatic). But there are lasers that produce light across a broader spectrum, or on a multiple of (specific) frequencies, depending on the laser. A link is provided below to the Wikipedia post on the laser.AnswerA laser produces an infinite number of wavelengths, but they are all very close to a characteristic single value. AnswerIf the laser is pulsed then the shorter the pulse the larger the bandwidth (the range of frequencies) of the pulse. Femtosecond (one thousandth of a billionth of a second) pulses produce "white" laser light which contains all the visible frequencies.
Is poly chromatic light can be coherent?
Coherent light (like a laser) is a single frequency. Polychromatic light is, by definiation, multiple frequencies and cannot be coherent.
What devices convert light energy into sound energy?
laser microphone
What type of energy is used in laser light?
Electrical (electromagnetic) energy is used. Light energy ( another form of electromagnetic energy) is produced.
What is light frequencies?
The frequency of a wave of light is given by speed of light/wavelength, or by energy/Planck's constant.If you know the frequency or the energy associated with the light, it is easily calculated.
How does radio frequencies produce radiation levels?
radiation just means energy that travels. radio waves are just a type of radiation, so is visible light. anything that radiates, including heat, is radiation.
How does a laser work in a short sentence?
Examples are: A laser is a small light that puts atoms to their highest energy power.
How do atoms emit line spectrums following excitation?
When electrons in an atom give up energy by dropping from a higher energy state to a lower energy state, that energy is emitted as photons of light whose frequencies are the lost energy/ Placvk's constant.As the atom can have several levels of energy, a spectrum of several lines is produced.
