Question

plz, and fast.



if you answered so thank you​

Answer 1

Answer:

Sin i / Sin r = Refractive index

= sin i / sin 30° = √3

= sin i = √3 /2

∴ i = 60°

∴ Angle of incidence = 60°

HOPE THIS HELPS YOU......

PLZ MARK AS BRAINLEST.....

Answer 2

Answer:- i = 60°

Solution:-

n = sin i / sin r

• √3 = sin i / sin 30°
• √3 = sin i / (1/2)
• √3 = 2 sin i
• sin i = √3/2
• i = arcsin (√3/2)
• i = 60°
