WILL GIVE BRAINLIEST TO THE MOST CORRECT ANSWER The angle of incidence of a ray of light striking an equilateral triangular prisms ABC of refracting angle 60o is 40o. Calculate:

(i)the angle of refraction at the first face
(ii)the angle of emergence
(iii)if the light is incident normally on the first face AB, with the aid of a ray diagram, describe the path of this light as it passes through the prisms. Take μ = 1.5.

What type of nuclear decay causes the atomic number of an element to increase by 1?

People with normal vision cannot focus their eyes underwater if they aren't wearing a face mask or goggles and there is water in contact with their eyes. in a simplified model of the human eye, the aqueous and vitreous humors and the lens all have a refractive index of 1.40, and all the refraction occurs at the cornea, whose vertex is 2.60 cm from the retina. with the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 2.05cm in front of the eye.)
