Curvature

Question 1

What is the main aim of the course OPH102?

Answer 1

To introduce students to curvature and to consider what happens to Snell’s law at a curved surface

Additionally, it provides a template for focusing light.

Question 2

What will students be able to define after completing the course?

Answer 2

Curvature

This includes understanding its implications in optics.

Question 3

What concept will students understand regarding light in OPH102?

Answer 3

How light refracts at a curved surface

This is essential for understanding optical systems.

Question 4

What notation will students learn to use in the course?

Answer 4

Cartesian notation

This is important for mathematical descriptions in geometry.

Question 5

What equation is fundamental for refraction at a spherical surface?

Answer 5

n’/ℓ’ = n/ℓ + (n’ – n)/r

This is a reformulation of Snell’s law for curved surfaces.

Question 6

Fill in the blank: Snell’s law becomes a fundamental paraxial equation for refraction at a spherical surface, represented as _______.

Answer 6

n’/ℓ’ = n/ℓ + (n’ – n)/r

Question 7

What is the primary focus of the course regarding light?

Answer 7

Framework for focusing

This involves understanding how curvature affects the path of light.
