## Study Notes

### Types of Mirrors and Their Uses

• Concave mirrors are commonly used in torches, search-lights, and vehicle headlights due to their ability to focus light into a parallel beam.
• Large concave mirrors are utilized in telescopes and solar concentrators to gather and concentrate light for better viewing and energy efficiency.

### Concave Mirrors in Dentistry

• In dentistry, concave mirrors are employed to provide magnification and improved visibility of oral cavities, enhancing the effectiveness of dental procedures.

### Spherical Mirror Magnification

• The magnification produced by a spherical mirror depends on the object's position relative to the focal point and the mirror's curvature, affecting the size and clarity of the resulting image.

### Light Ray Behavior at Media Boundaries

• When a light ray travels obliquely from a rarer medium (like air) to a denser medium (like glass or water), it bends towards the normal line, altering its path.

### Lens Formula Relationships

• The lens formula states that the relationship between the object-distance (u), image-distance (v), and focal length (f) of a spherical lens is represented by the equation: 1/f = 1/v - 1/u.
