Why does the radiometer spin when light shines on it?
The solar energy is changed first to thermal energy, and then to kinetic energy. A partial vacuum inside the radiometer glass allows the vanes to spin easily. The brighter the light, the more heat energy is transferred, and faster the vanes will rotate.

What is a light radiometer?
The radiometer is a light bulb-shaped device containing an object that looks like a weather vane (wings arranged in a circle like spokes of a wheel). Developed to measure the intensity of radiant energy, or heat, the radiometer will: Help you understand the principles of energy conversion.
What is a radiometer used for?
Radiometer is a device used to measure the intensity of radiant energy. A majority of radiometers use only single photocell sensors. In order to measure radiation emitted from a specific spectrum or to incorporate the radiometer within a certain spectral response, an optical filter is normally used.
How does a microwave radiometer work?
The microwave radiometer (MWR) provides time-series measurements of column-integrated amounts of water vapor and liquid water. The instrument itself is a sensitive microwave receiver that detects the microwave emissions of the vapor and liquid water molecules in the atmosphere at two frequencies: 23.8 and 31.4 GHz.
Which way does a radiometer spin?
When the radiometer is heated in the absence of a light source, it turns in the forward direction (i.e. black sides trailing). If a person’s hands are placed around the glass without touching it, the vanes will turn slowly or not at all, but if the glass is touched to warm it quickly, they will turn more noticeably.
How does a Sun Spinner work?
A Crookes’ radiometer has four vanes suspended inside a glass bulb. Inside the bulb, there is a good vacuum. When you shine a light on the vanes in the radiometer, they spin — in bright sunlight, they can spin at several thousand rotations per minute!
How does a light spinner work?
When you shine a light on the vanes in the radiometer, they spin — in bright sunlight, they can spin at several thousand rotations per minute! If the vanes have a frictionless support and the vacuum is complete, then photons bouncing off the silver side of the vanes push the vanes, causing them to rotate.

Where does the sun shine at the equinox?
At the equinox, the Sun’s rays shineon the equator, and the Northern andHemispheres get the same amount
How are diamond wings powered by the Sun?
It’s the spear powered by the sun! When light strikes the diamond wings it tranfers heat to each one, but not to the same degree. The light wing reflect the rays and the darker wing absorbs the rays. The stronger the light the more energy there is to heat up the darker side causing the wings to spin faster.
Where does the sun shine most directly on Earth?
, the Sun shines most directly on the Tropic of Cancer, 23.5 degrees north of the equator, giving its most direct energy on Earth to the Northern Hemisphere. During the winter solstice, the Sun shines most directly on the Tropic of Capricorn, 23.5 degrees south of the equator, giving its most direct energy on Earth to the Southern Hemisphere.
