Luminance response can be tested with a(n) _____. i. near-range photometer ii. telescope photometer iii. illuminance meter
Furkat [3]

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

Lady bird [3.3K]

Answer:

Tissue

Explanation:

A cell is a structure formed during the evolution which contained all the molecules and favourable conditions required to survive and therefore acts as the functional and structural unit of life.

In evolution, more than one cell aggregated together to form a structure which could perform much complex function than a single cell called tissue as they are programmed to perform the same function.

In the given question, since the heart cells worked together to cause movement in the robot therefore the cardiac cells formed cardiac tissue or heart.

Thus, the tissue is the correct answer.
