1.Units, Dimensions and Measurement
medium
Dimensions of luminous flux are
A$M{L^2}{T^{ - 2}}$
B$M{L^2}{T^{ - 3}}$
C$M{L^2}{T^{ - 1}}$
D$ML{T^{ - 2}}$
Solution
Luminous flux is nothing but power per unit time. Its dimension is equal to the dimension of
power.
luminous flux $=$ power $=\left[M L^{2} T^{-3}\right]$
power.
luminous flux $=$ power $=\left[M L^{2} T^{-3}\right]$
