MLT are are the dimersions of
Correct answer: D. All of these
- A. strain
- B. refractive index
- C. magnification
- D. All of these
Explanation
The given dimensions indicate a dimensional quantity. Strain = change in length/original length [L]/[L] =1 so it is dimensionless Refractive index = velocity of light in medium 1/ velocity of light in medium 2 [LT-1]/[LT-1]=1 so it is dimensionless Magnification=Image length/ Object length [L]/[L] = 1 so it is dimensionless As all these quantities have no dimensions, option D is correct.
