MCQ
Dimensions of luminous flux are
- A$M{L^2}{T^{ - 2}}$
- ✓$M{L^2}{T^{ - 3}}$
- C$M{L^2}{T^{ - 1}}$
- D$ML{T^{ - 2}}$
✓
Answer
Correct option: B.
$M{L^2}{T^{ - 3}}$
b
Luminous flux is nothing but power per unit time. Its dimension is equal to the dimension of
power.
Luminous flux is nothing but power per unit time. Its dimension is equal to the dimension of
power.
luminous flux $=$ power $=\left[M L^{2} T^{-3}\right]$
