Write dimensional formula for the intensity of radiation.
- A \(\mathrm{M}^{1} \mathrm{~L}^{0} \mathrm{~T}^{-3}\)
- B \(\mathrm{M}^{3} \mathrm{~L}^{2} \mathrm{~T}^{1}\)
- C \(\mathrm{M}^{1} \mathrm{~L}^{2} \mathrm{~T}^{3}\)
- D \(\mathrm{M}^{0} \mathrm{~L}^{2} \mathrm{~T}^{-3}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{M}^{1} \mathrm{~L}^{0} \mathrm{~T}^{-3}\)
Step-by-step Solution
Detailed explanation
A.\(M ^1 L ^0 T ^{-3}\)
વિકિરણની તીવ્રતા = \(=\frac{\text { power }}{\text { time × area }}\)
\(1=\frac{ M ^1 L^2 T^{-2}}{T^1 \times L ^2}\)
\(I=M^1 L^0 T^{-3}\)
વિકિરણની તીવ્રતા = \(=\frac{\text { power }}{\text { time × area }}\)
\(1=\frac{ M ^1 L^2 T^{-2}}{T^1 \times L ^2}\)
\(I=M^1 L^0 T^{-3}\)
