Physics Waves and Optics
Could anyone please help with this?
Consider a transparent spherical rubber balloon filled with air. The outer diameter of the balloon is 𝐷=20 cm and the thickness of the walls is 𝑡=50 micrometres. The refractive index of air is 𝑛a=1.000 and the refractive index of rubber is 𝑛𝑟=1.510. Use the paraxial approximation in your calculations.
a) Find the focal length of the optical system formed by the walls of the balloon. The focal length is measured with respect to the centre of the balloon
