This picture below is the pictorial representation of the anatomy of the eye: I have put this picture at the beginning so that you can understand what I'll be speaking about in the rest of the answer. The picture shows light entering

The total energy of all the light given off is termed the “luminous flux.”. One candela per steradian is termed a lumen, which is the measure of light intensity people are most familiar with. However, what matters most in terms of measuring light intensity is the number of lumens falling on a surface, which is expressed as lux.

Light, Temperature and Humidity. Light is an essential factor in maintaining plants. The rate of growth and length of time a plant remains active is dependent on the amount of light it receives. Light energy is used in photosynthesis, the plant’s most basic metabolic process. When determining the effect of light on plant growth there are ...

In photometry, luminous intensity is a measure of the wavelength-weighted power emitted by a light source in a particular direction per unit solid angle, based on the luminosity function, a standardized model of the sensitivity of the human eye. The SI unit of luminous intensity is the candela (cd), an SI base unit. Photometry deals with the ...

Humans can't hear all sounds. Actually, not even most, in the grand scheme of things. Like how we can only see a narrow band of all wavelengths--hence "visible" light--we can also only hear some of the possible ...
