Question

write the formula for object in denser medium and image is rarer medium or denser to rarer​

Answer 1

Answer:

the formula for refractive index when light travels from rarer to denser medium is

sinisinr

sin⁡isin⁡r

where i=i= angle of incidence, r=r= angle of refraction.

Is the same formula used for calculating refractive index when light travels from denser to rarer medium? Or is it

sinrsini
