Answer:
The angular range in which the fish can see above water surface will be 98°
Step-by-step explanation:
critical angle = angle that the light ray in one side will make with the water surface
This angle will be equal to half the range in which the fish can see
=> angle range = 2 x critical angle
= 2 x 49
= 98°
Hence The angular range in which the fish can see above water surface will be 98°
