A light meter is used to measure the amount of ambient and reflected light in Photography. This helps to determine the proper exposure for a photograph. A company called Weston marketed the first photographic light meter in 1932.

How can I measure the amount of blue light exposure using a blue light meter?
To measure blue light exposure using a blue light meter, simply point the meter towards the light source and take a reading. The meter will provide a numerical value indicating the intensity of blue light present. This value can help you track and monitor your blue light exposure over time.
How is Energy transferred to a light meter?
Energy is transferred to a light meter through the incident light that falls on its sensor. The sensor then converts the light energy into an electrical signal that is proportional to the intensity of the light. This electrical signal is used to determine the light level and provide a reading on the light meter.
Why might a scientist use a light meter?
A scientist might use a light meter to measure the intensity of light in a particular environment. This can help them understand how light levels may affect biological processes, growth patterns, or the behavior of organisms.
How do you measure light intensity and what tools or methods are commonly used for this purpose?
Light intensity is measured using a device called a light meter, which detects the amount of light in a given area. Common methods include using a digital light meter, a lux meter, or a spectrophotometer to measure light intensity in units such as lux or lumens.
How do you use a light intensity meter?
To use a light intensity meter, first turn it on and hold it in the area you want to measure. Make sure it is facing the light source directly. Take a reading of the light intensity and note the value displayed on the meter.
Who invented the first light meter?
The first handheld light meter was invented by Arthur James Dalladay in 1932. He created a light meter that photographers could use to measure the intensity of light for more accurate exposure settings.

How to use a light meter with a film camera?
To use a light meter with a film camera, follow these steps: Set the ISO/ASA on the light meter to match the film speed of your camera. Point the light meter towards the subject you want to photograph. Press the button on the light meter to measure the light. Adjust the aperture and shutter speed on your camera based on the light meter reading. Take the photo using the settings recommended by the light meter. Remember to adjust the settings as needed for different lighting conditions.
Who invented the lux meter?
Lux meter is a term sometimes used to refer to a light meter. If you mean who invented the light meter, Weston marketed the first photographic selenium meter in 1932, which was not well received. Dr. Bruno Lange is also credited with inventing a much more practical version in 1933 and started a company that year. I believe both of these versions were exposure meters and not designed to simply measure illumination. The meter has gone through various improvements for which patents have been granted for, thus there is more than one inventor of a light meter (Joseph Hostetter applied for a patent for a type of light meter in 1974). Lux is the metric version of the Imperial measurement called foot candle, which is based on the level of visible light at a point that is one foot away from one candle and spread out over one square foot. Although lux was a known quantity much earlier than the invention of the meter, would not be until the use of modern materials made light measurement possible using electronic means.

What is a light meter used for?
If you mean a light meter that is used in a photographic studio, then it measures the light that hits the 'subject' from the studio lighting, the light meter then tells you what you need to set your camera to, for the correct exposure.
