optical pyrometer
A special type of technique is used to measure very high temperatures such as the Sun. A Bolometer is the instrument used to measure the Suns temperature. The Bolometer measures in colors, and the Sun emits temperatures in colors. This technique is based on a law called Wien's Law.
What else can I help you with?
What is a unit used to measure the large distances between objects in our solar system?
The Astronomical unit is used to measure the large distances in our solar system. It is roughly the average distance between the Earth and the Sun.
Which Four things used to measure time on earth are?
sundial, watch, clock, calendar, hourglass, egg timer, metronome, sun, moon........
What Does a sundail measure?
Time, It uses the Sun to cast a shadow.
How does temperature change with the seasons?
When the Earth orbits the sun different sides of the earth face the sun.Therefore changing the temperature.
How many mm is 1 degree?
A mm is a measure of linear distance whereas a degree is a measure of angular distance. The two measure different things and there is no direct conversion from one to the other. For example, the angular measure across the full moon and the sun re approximately the same (which is why you can have the total solar eclipse with the solitaire) but there is a huge difference in the size of our two cosmic neighbours!
If thermometer is placed in sun light then which thing it will read the temperature of air or of sun or surrounding?
A thermometer placed in sunlight will measure the temperature of the air surrounding it, not the temperature of the sun itself. The sun's rays can heat up the air, which in turn affects the temperature measured by the thermometer.
Is the thermometer reading the temperature of the vacuum at the Moon's surface?
No. The thermometer measures the temperature of mass or material. Concerning the moon, a thermometer could measure the temperature of dust or rock on the surface. If it were not in contact with the surface, and the sun shone on it, the thermometer would read the temperature to which the sun heated it. If it were shielded from the sun, then the thermometer would read the temperature of space ... about 3 K, or darn near absolute zero.
When thermometer is laid ouside the sun does it measure suns temperature or air temperature?
If a thermometer is laid out in direct sunlight, it will not measure the temperature of the air surrounding it. It will measure the temperature of the heat directly reaching it.
What do you use to measure the energy from the sun?
One common instrument used to measure the energy from the sun is a pyranometer. Pyranometers are designed to measure the solar radiation flux density, which represents the amount of energy received from the sun per unit of time and area.
Was the sun dial an early temperature thermometer?
No. The sun dial was an early device to help tell time.
What is recording earth thermometer?
the earth thermometer measures air temperature.to forecast air temperature accurately,forecasters put he thermometer in a little house-like container.this containerhas openings on all sides to allow air to flow through.the earth thermometer must be protected from the sun.
What happens when a thermometer is left in sunlight?
When a thermometer is left in sunlight, it can absorb heat and give a falsely high temperature reading due to radiant energy from the sun. It's important to shield the thermometer from direct sunlight to get an accurate temperature measurement.
How you can measure the temperature of the sun?
You certainly can't take a thermometer there - any thermometer will vaporize rather quickly at the high temperatures of the Sun. The temperature of the Sun's surface (the visible part) can be calculated on the basis of the light emitted by the Sun - especially by analyzing the Sun's spectrum. At a different temperature, it would emit a different mix of wavelengths. The temperature in the Sun's core has to be calculated theoretically, on the basis of our knowledge of physics. The Sun's diameter, its mass, the age of the Solar System (estimated by the age of the Earth) and the Sun's composition (what percentage of the different elements it has) all enter this calculation. The composition of the Sun's interior must also be estimated, based on what is visible on the outside. Computer simulations are used in such calculations; the main cause of possible error is our understanding of physics - note that the conditions in the interior of the Sun are very extreme - the temperature is estimated to be several million degrees, and the pressure is very extreme as well.
Where should you put your thermometer in shade or sun?
It is best to place your thermometer in the shade to get an accurate reading of the air temperature. Direct sunlight can affect the reading by warming up the thermometer and giving a higher temperature measurement.
How measure the sun temperature?
Use a spectrometer to measure the wavelength of the light. There is a direct, but inverse correlation of the wavelength to the temperature.
What was the difference between the thermometer readings in the drawer and in direct sunlight?
The thermometer readings in the drawer were typically lower than in direct sunlight. This is because objects in the drawer are shielded from direct heat and radiation from the sun, resulting in a cooler temperature reading.
What is being measured by an outdoor thermometer?
If it's in the shade, then the temperature of the air that wafts past it is. If it's in direct sun, then it's displaying the temperature of the structure of the thermometer itself, as it absorbs direct solar radiation and its temperature rises above that of the air that wafts past it.
