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.

∙ 14y agoRadiometers spinbecause of the solar energy that bounces of from the flags in the radiometer. The light does not push it because it does not have arms but the radiometer is solar powered. Solar powered means that you get energy from the light of the sun.

What happens after the light is absorbed by a radiometer?
The light energy is absorbed and dispersed after it hits the radiometer.
What effect does the light source have on a radiometer?
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 is a device that contains vanes that move when exposed to light?
radiometer
What kind of energy powers a radiometer?
Geothermal
What energy transformation are taking place with the radiometer?
potential --.
Why does a radiometer spin when a light is flashed on?
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.
What happens after the light is absorbed by a radiometer?
The light energy is absorbed and dispersed after it hits the radiometer.
Can mechanical energy turn into light energy?
Light can excite molecules which can generate a force. One example is the pressure differential produced inside a radiometer, causing it to spin.
What converts light into mechanical energy?
A radiometer
What effect does the light source have on a radiometer?
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 is a device that contains vanes that move when exposed to light?
radiometer
How can magnetic energy be converted to mechanical energy?
In an internal combustion engine, you change energy in the gasoline to mechanical energy
In a Radiometer which vane absorb the most light energy?
you have a force field that the first vane you can tell it
How many electrons are emitted when calcium is flashed with light of wavelength 340 nm and intensity of 50 percent?
5 electrons are emitted when calcium is flashed with light of wavelength 340 nm and intensity of 50 percent.
What is a sentence with the word radiometer?
The lamp is then scanned using a filter radiometer under computer control.
What device converts mechanical energy to light energy?
you can use generator which covert mecahnical energy to electric energy .......
Can you get flashed by a camera on traffic lights?
Yes if you run a red traffic light (in the UK)
