Why is it important for light energy to be absorbed in a radiometer?
In a radiometer, light energy is absorbed by the vanes, causing them to heat up. This creates a temperature difference between the inside and outside of the vanes, leading to a pressure difference that causes them to spin. Absorption of light energy is crucial for the radiometer to convert light into mechanical energy and demonstrate its functionality.
What is the relationship between the intensity and energy of light?
The relationship between the intensity and energy of light is that the intensity of light is directly proportional to its energy. This means that as the intensity of light increases, so does its energy.
What is the process of energy transfer that does not occur due to a temperature difference?
The process of energy transfer that does not occur due to a temperature difference is called radiation. Radiation is the transfer of energy through electromagnetic waves, such as light or microwaves, without the need for a difference in temperature between the objects involved.
What is the difference Between Light energy and Radiant Energy?
Light energy refers specifically to the visible spectrum of electromagnetic radiation that can be perceived by the human eye, while radiant energy is a broader term that encompasses all forms of electromagnetic radiation, including light as well as non-visible forms such as infrared, ultraviolet, and radio waves. Essentially, light energy is a subset of radiant energy.
What is the difference between light energy and solar energy?
Light energy refers to electromagnetic radiation that can be seen by the human eye, while solar energy specifically refers to the energy derived from the sun's electromagnetic radiation. Solar energy encompasses a broader spectrum of energy that includes both light energy and non-visible forms of energy such as infrared and ultraviolet radiation.
What is the difference between the energy of ultra violet light and the energy visible light?
Ultraviolet light has a greater energy per photon.
What is the Difference between the thunderstorms and lightning?
Lightning is light energy, or electromagnetic energy. And thunder is sound energy.
Differences between LED and photodiode?
The Simplest Difference is that LED emits Light, & Photodiode converts Light energy into electrical Energy
Why do electrons emit light when they fall down to their ground state?
When electrons fall down to their ground state, they release energy in the form of photons of light. This is because the energy difference between the higher energy state the electron was in and the ground state is emitted as light. The wavelength of the light emitted depends on the specific energy difference between the two states.
What is the difference between potential energy and light energy?
They are two completely different things. Light energy is electromagnetic waves. (EM). Potential energy is the energy stored within matter.
What is the difference between the red and blue colors of light?
Wavelength Frequency and Photon Energy
what is Difference between heat and light?
Light is electromagnetic waves that carry energy in the form of photons from one place to another whereas heat is the energy that moves from one place to another due to a temperature difference between the two points.
What is the difference between T12 and T8 fluorescent light bulbs?
The main difference between T12 and T8 fluorescent light bulbs is their size and energy efficiency. T12 bulbs are larger and less energy efficient compared to T8 bulbs, which are smaller and more energy efficient.
Why is it important for light energy to be absorbed in a radiometer?
In a radiometer, light energy is absorbed by the vanes, causing them to heat up.

Absorption of light energy is crucial for the radiometer to convert light into mechanical energy and demonstrate its functionality.
What is the different between energy saving light bulbs and original light bulbs?
The difference between the two bulbs is that energy saving bulbs have murcuary in them which lowers the amount of electricity they require and consume.
What is the difference between energy and light?
Light is one of many forms of energy. Heat, motion, sound, potential energy (which can be mechanical, chemical, or nuclear) and many other types of energy also exist.
How is light formed in terms of energy levels?
Light is formed when an electron in an atom moves from a higher energy level to a lower energy level. This movement of the electron releases energy in the form of photons, which are what we perceive as light. The energy of the photon is directly related to the difference in energy between the two levels the electron transitions between.
