Exercises: 1. Consider a lens with a focal length of 75 mm surrounded by air. An object with height of 5 mm is located 150 mm to the left of the lens. Calculate the position and height of the image. 2. Consider an object 2 cm tall object located 6 m to the left a -2D spectacle lens. Calculate the position and height of the image. 3. Assume that the anterior radius, posterior radius and thickness of the lens are 9.4 mm, - 5.6 mm, and 3.5 mm respectively when the eye is relaxed, and 5.8 mm, -5.0 mm and 4.2 mm, respectively when the eye is accommodated. Calculate the power of the lens in the relaxed state and the accommoJated state. You can assume that the lens has a refractive index of 1.415 and that aqueous and vitreous have a refractive index of 1.336. ed 141 KB 13% o search

Q: Why can't flat lenses focus light?

A: Flat lens have infinite radius of curvature. Hence, their focal length is also infinite.

Nature of light

Light is transverse and electromagnetic radiation that exhibits the properties of a wave as well as a particle. For this reason, light is said to have a “dual nature.”
