Luminance response can be tested with an option(d) I or II i.e, near range photometer or telescope photometer.
The luminous intensity per unit area of light traveling in a specific direction is measured photometrically as luminance. It indicates how much light enters, exits, or is reflected from a specific area and falls within a specified solid angle.
The visual system's ability to function depends heavily on luminance and contrast. Vision is impossible without light (luminance = 0), and without contrast, we are unable to see spatial or temporal patterns. The first stage in seeing, which enables all other visual processes, is the capacity to respond to brightness.
A photometer is a tool used to gauge light's characteristics. A photometer can be used to measure a light source's brightness, color, and flux among other attributes. Photometers gather radiation released by the light source to determine the wavelengths of light and atomic emissions.
The complete question is:
Luminance response can be tested with a(n)_____.
I) near-range photometer
II) telescope photometer
III) illuminance meter
A) I only
B) II only
C) III only
D) I or II
