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.
Radiometers 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.

The light energy is absorbed and dispersed after it hits the 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.

Light can excite molecules which can generate a force. One example is the pressure differential produced inside a radiometer, causing it to spin.

radiometer
In an internal combustion engine, you change energy in the gasoline to mechanical energy
you have a force field that the first vane you can tell it
5 electrons are emitted when calcium is flashed with light of wavelength 340 nm and intensity of 50 percent.
The lamp is then scanned using a filter radiometer under computer control.
you can use generator which covert mecahnical energy to electric energy .......
Yes if you run a red traffic light (in the UK)
