The heat from the sun makes the particles vibrate and move and then it make the thing spin. In the shade it doesn't move because the particles aren't moving.

What kind of energy powers a radiometer?

A radiometer is powered by light energy. When light is absorbed by the vanes of the radiometer, it creates a temperature difference that causes the vanes to rotate. This rotation is a demonstration of the conversion of light energy into mechanical energy.


What energy transformation are taking place with the radiometer?

In a radiometer, light energy is converted into rotational kinetic energy. The light causes the vanes inside the radiometer to spin due to the pressure exerted by the photons on the reflective surfaces of the vanes.


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 energy transformation for radiometer?

In a radiometer, light energy is converted into kinetic energy. When light is absorbed by the dark side of the vanes, it causes the molecules inside to heat up and move faster, resulting in the rotation of the vanes.


What happens after the light is absorbed by a radiometer?

After the light is absorbed by a radiometer, the black and white vanes inside start to rotate due to the thermal expansion of the air molecules around them. The rotation occurs because the black side absorbs more light and heats the air more than the white side, causing a pressure difference that drives the movement.

Is rainbow source of light?

No, a rainbow does not produce light, it is an effect of light being bent (refracted). The source of the light seen in a rainbow is the Sun.

Why does a radiometer spin when a light is flashed on it?

The shiny side of the vanes reflects the heat from the light, while the black side absorbs it. As it absorbs the light and heat, it also heats the air molecules near it. This cause the air molecules to exert a tiny bit of pressure on the flags, enough to make them spin.


Do different color lights have an effect on radiometers?

Yes, different color lights can have an effect on radiometers because radiometers are sensitive to the wavelength of light. Radiometers designed to measure specific wavelengths will react differently to different colors of light. It is important to use the correct type of radiometer for the desired measurement.


Why would the vanes rotate faster if the brighter light source is used?

The vanes of a radiometer rotate faster when a brighter light source is used because the light exerts more energy on the blackened side of the vanes, causing them to heat up and create a temperature difference that drives the rotation due to the momentum transfer of gas molecules. This results in increased kinetic energy and faster rotation.
