speed c: light in vacuum to the speed of light in glass,)is found to vary with the

wavelength µ = A + B/λ2

where A and B are constants. Using the principle of homogeneity determine the

dimensions and SI units of A and B

Please explain each and every step with reason as i coudn't understand the steps of this in NCERT

Pls don t add a hyperlink, but solve , thank u

If P,Q,R are physical quantities, having different dimensions, which of the following combinations can never be a meaningful quantity (a) (P-Q)/R (b) PQ-R (c) PQ/R (d) (R+Q)/Pvertices of a regular hexagon. The electric field

strength at centre is E. If –Q charge is removed,

then electric field strength becomes E′. E′ is equal

to

(1) Zero (2) 2E

(3) E (4) 2E

pls answer the question with the same values , don'thyperlink a sum of the same kind.

Thank u sooo much

^{2})/at where E is energy, x is distance and t is time.I attended the unit and measure test- i could get only 66% - need your help to enhance my score..

Want your feedback on the area of improvement.
