A pyranometer is the instrument used for measuring the intensity of sunlight. It measures the total solar radiation flux density in watts per square meter.
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
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.
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.
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.
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.

A backstaff is a an early navigational instrument for measuring the altitude of the sun and hence calculating latitude.
It is a mediaeval instrument for measuring the altitude of the sun and other sky objects, now replaced by the sextant.
A sun recorder is a weather instrument that records the number of minutes or hours per day in which the sun's rays are present to the degree capable of burning through a paper recording strip, when magnified through a glass sphere.

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.
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.
Sunlight is light.The word has been added as the light comes from the sun.Light is measure in candela as a unit ofmeasurement.A Lux meter is used to measure light in the unit of candela.
The cross staff was used to determine the vessels latitude by measuring the altitude of Polaris or the Sun.
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.
