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.”

Question

Optics?

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.
