Question

Luminous Intensity is expressed in a unit named :

A.

Tesla

B.

Candela

C.

Angstrom

D.

Newton

Correct option is B

The correct answer is (B) Candela

Explanation:

Luminous Intensity is the measure of the perceived power of light emitted by a source in a specific direction, and it is expressed in the unit of Candela (cd). One candela is approximately the luminous intensity of a single candle.

Information Booster:
  1. Candela is one of the seven base units in the International System of Units (SI).

  2. The unit Candela is used to measure the intensity of light as perceived by the human eye.

  3. It is defined as the light emitted by a source in a particular direction.

  4. Candela is based on the light intensity emitted by a small, standardized source of light.

  5. It is crucial in fields such as photometry and lighting design.

  6. The measurement is important for applications related to the visual effects of lighting.

Additional Information:
  •  Tesla – Tesla is the unit of magnetic flux density, not related to luminous intensity.

  •  Angstrom – Angstrom is a unit of length used in measuring wavelengths of light, not luminous intensity.

  •  Newton – Newton is the unit of force, unrelated to the measurement of light intensity.
