What does a heliograpgh measure?
A signalling device, sunlight is reflected in flashes from a movable mirror. Or it can be a telescopic apparatus for photographing the sun Or an instrument for recording the duration and intensity of sunshine
How do you increase sunlight intensity?
A lens can be used to concentrate light. A group of mirrors aimed at the same location as they track the Sun would increase its' intensity. Upto 7000 degrees.
How does light intensity and the rate of photosynthesis relate to the position of the sun?
The angle and intensity of sunlight affect the rate of photosynthesis in plants. Plants positioned in direct sunlight receive higher light intensity and thus have a higher rate of photosynthesis compared to shaded plants. The position of the sun in the sky also determines the light angle and intensity that plants receive, influencing their photosynthetic rate.
What instrument is UV RAYS used?
UV rays are not produced by any musical instrument. UV rays are a form of electromagnetic radiation that comes from the sun and can cause skin damage and other health issues.
What is the function of UV spectrometer?
Spectroscopes are used to determine the elements present in different substances. They do this by separating light into spectra, or different colors. Each element has a unique spectra, just like people each have a unique fingerprint. By looking at the light from a star, for example, a scientist can tell that it contains hydrogen, helium, and other elements. It was discovered that our sun contained helium by using a spectroscope during an eclipse- this was before we'd even discovered helium on earth! Spectroscopes can be used to tell the chemicals that are present in your blood. They can be used to determine if a molten metal is at the correct temperature for an industrial process, and can confirm the percentages of metals in an alloy.
What is instrument is used for measuring the pressure of the atmosphere?
sun
What was the first instrument used for measuring time?
The sun.
What is the instrument for measuring the pressure of the atmosphere?
sun
What is a backstaff?
A backstaff is a an early navigational instrument for measuring the altitude of the sun and hence calculating latitude.
What does the astrolabe measure?
It is a mediaeval instrument for measuring the altitude of the sun and other sky objects, now replaced by the sextant.
What is a sun recorder?
A sun recorder is a device used to measure the duration and intensity of sunlight. It typically consists of a rotating drum with photosensitive paper that records the sun's movement and intensity throughout the day. This data can be used for various purposes such as climate studies and monitoring solar energy potential.
What does a heliograpgh measure?

What instrument measures the altitude of the sun?
A sun altimeter, also known as a solar altitude instrument, is commonly used to measure the altitude of the sun. This instrument can help determine the sun's position in the sky, which is important for various applications such as navigation, astronomy, and solar energy systems.
What is sun's intensity?
The intensity of the sun's radiation refers to the amount of energy it emits per unit area per unit time. The intensity of the sun's radiation is highest at the surface of the sun and decreases as it travels through space. At the Earth's surface, the intensity of solar radiation is about 1,000 watts per square meter on a sunny day.
What physical law describes the manner in which the intensity of sunlight changes as the observer moves away from the sun?
The physical law that describes how the intensity of sunlight changes as the observer moves away from the sun is known as the inverse square law. This law states that the intensity of sunlight decreases in proportion to the square of the distance from the sun. This means that the farther away an observer is from the sun, the weaker the intensity of sunlight they will experience.
What is the instrument used for measuring sunlight?
A pyranometer is an instrument used to measure the total solar radiation received from the sun, typically expressed in watts per square meter. It is designed to capture both direct and diffuse sunlight.
What was a cross staff used for?
The cross staff was used to determine the vessels latitude by measuring the altitude of Polaris or the Sun.
