What is the law of reflection?

The angle of incidence is equal to the angle of reflection.

The angle of incidence is half the angle of reflection.

The angle of incidence is always greater than the angle of reflection.

Explain Snell's Law and its significance in optics.

Snell's Law describes the relationship between the angles of incidence and refraction when light passes through different media.

Snell's Law is unrelated to the angles of incidence and refraction.

Snell's Law states that light cannot pass through any medium.

Snell's Law only applies to sound waves.

Describe the difference between concave and convex mirrors.

Concave mirrors create virtual images; convex mirrors can create real images.

Concave mirrors diverge light and create virtual images; convex mirrors focus light.

Concave mirrors reflect light evenly; convex mirrors reflect light unevenly.

Concave mirrors focus light and create real images; convex mirrors diverge light and create virtual images.

How does the focal length of a lens affect image formation?

The focal length affects the size, position, and type of image.

The focal length determines the weight of the lens.

The focal length only affects the color of the image.

The focal length has no impact on image clarity.

State the lens formula and explain its components.

1/f = v * u

1/f = 1/v + 1/u

f = v + u

1/f = 1/u - 1/v
