Question

explain the derivation of dimensional formula intensity of light, radiation pressure and speed of light?

Answer 1

Dear student,

Radiation pressure = $\frac{\left[\mathrm{Intansity}\mathrm{of}\mathrm{light}\right]}{\left[\mathrm{speed}\mathrm{of}\mathrm{light}\right]}=\frac{{\displaystyle \frac{\left[\mathrm{Energy}\right]}{\left[\mathrm{time}\right]\times \left[\mathrm{area}\right]}}}{\left[\mathrm{speed}\mathrm{of}\mathrm{light}\right]}=\frac{{\displaystyle \frac{{\mathrm{ML}}^2{\mathrm{T}}^{-2}}{{\mathrm{M}}^0{\mathrm{L}}^0\mathrm{T}\times {\mathrm{M}}^0{\mathrm{L}}^2{\mathrm{T}}^0}}}{{\mathrm{M}}^0{\mathrm{L}}^1{\mathrm{T}}^{-1}}={\mathrm{ML}}^{-1}{\mathrm{T}}^{-2}$
