Question

Match List-I with List-II:
List-I (Factor):
(A). Luminous Intensity
(B). Luminous Flux
(C). Luminance
(D). Illuminance
List-II (Unit):
(I). Lux (lx)
(II). Candela (cd)
(III). Lumen (lm)
(IV). cd/m2
Choose the correct answer from the options given below:

• A. (A)-(II), (B)-(III), (C)-(IV), (D)-(I)
• B. (A)-(I), (B)-(II), (C)-(III), (D)-(IV)
• C. (A)-(III), (B)-(I), (C)-(IV), (D)-(II)
• D. (A)-(III), (B)-(IV), (C)-(I), (D)-(II)

Hint:

To easily recall:
- Luminous Flux = total light output = Lumens (lm)
- Illuminance = light arriving at a surface = Lux (lx)
- Luminous Intensity = direction-based light = Candela (cd)

Answer 1

The Correct Option is A
