Question

Dimensional formula of magnification?? ​

Answer 1

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.

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]
