Question

does the snells law apply to spherical mirrors and lenses?​

Answer 1

Answer:

Yes! (I believe) Whichever "point" your light ray strikes at the curved interface (surface) just draw a tangent along that point of the surface. ... Hence, Snell's law of ray optics is valid for all the points on a curved surface (interface between the two optical media

Answer 2

The snells law is applied to spherical mirrors and lenses:

• Descartes' law is also referred to as the Snell–Descartes law.
• This formula describes the relationship between the angles of incidence and refraction when light or other waves travel through a boundary between two different isotropic media, such as water, glass, or air.

As a result, the answer to the given question is yes.
