Question

Please give me some important Formulas from 'Light Reflection & Refraction' Chapter,Class 10 to solve Numericals​

Answer 1

Answer:

reflection-1/f = 1/v–1/u

and m= h2/h1

or m= –v/u

refraction-¹n⬇2=1/¹n⬇2

n=c/v

sin i/sin r=n2/n1=¹n⬇2

HERE ARE THOSE IMPORTANT FORMULA YOU CAN REVISE FOR YOUR EXAMS!!

ALSO REMEMBER ONE THING YOU HAVE TO KEEP IN MIND THE RELATIVE REFRACTIVE INDEX OF WATER,AIR AND GLASS!!

Hope it helps!

Thank you!
