Question

write the dimensional formula for Magnification​

Answer 1

Answer:

magnification is dimensionless

Answer 2

Answer:

Magnification is the ratio between height of the image to the height of the object.

Hence, m = h'/h

Here, height is basically length in base quantity.

So, m = [L]/[L]

Here, the lengths will cancel out.

So, we can conclude that magnification is a dimensionless quantity.

_________

Dimensions of the base quantities and the combination of base quantities helps in recognising the nature of other physical quantities.

The principal for homogeneity of dimensions are used to check the correctness of the equation.

The physical quantities which have same dimensions can be added or subtracted together.

The physical quantities which do not have same dimensions, no calculations can be done between them.
