What do light sensors measures?
Light sensors measure the number of photons or the energy of light hitting the sensor.
A spectroscope measures the light energy given off by?
orbital electrons
How is Energy transferred to a light meter?
Energy is transferred to a light meter through the incident light that falls on its sensor. The sensor then converts the light energy into an electrical signal that is proportional to the intensity of the light. This electrical signal is used to determine the light level and provide a reading on the light meter.
What units of measurement does a spectrometer use?
A spectrometer measures the wavelength, wave number, and photon energy of light. They are measurements of the type and energy levels of light.
Is light thermal energy?
Thermal energy is not light. It is heat! Energy of heat and temperature of matter (more heat=more thermal energy=more movement of molecules) Temperature measures movement of molecules
What instrument measures molecular energy?
A thermometer measures molecular energy.
What are 3 possible measures for the base and the height of a triangle?

What is the unit of sound and light?
Several units are used, depending on what you want to measure. For example, in the case of sound, you can use units of energy, of intensity (energy/area), of wavelength, frequency, speed, and probably a few more.
What does blinding energy measure?
Blinding energy measures the power output of a light source, typically expressed in lumens or lux. It quantifies the brightness level produced by the source and can help determine the light intensity perceived by an observer.
What does a light wave measure?
A light wave measures the oscillation or vibration of electric and magnetic fields as it travels through space. It carries energy and information in the form of electromagnetic radiation.
Why does heat and light doesn't have mass?
Heat and light do not have mass because they are forms of energy rather than matter. Mass is a property of matter that measures the amount of substance in an object, while heat and light are forms of energy that result from the movement and interactions of particles at the atomic or subatomic level.
What is the difference between absorbance and transmittance?
Absorbance measures the amount of light absorbed by a sample, while transmittance measures the amount of light that passes through a sample. Absorbance is calculated as -log(T), where T is transmittance. Absorbance is commonly used in spectrophotometry to quantify the concentration of a substance in a solution.
