GEOMETRIC OPTICS

What is the primary focus of geometric optics?

• The study of light's wave properties

• The study of light's interaction with matter

• The study of light's rays, reflection, and refraction

• The study of light's rays, reflection, and refraction

Which of the following is true according to the law of reflection?

• The angle of incidence equals the angle of reflection

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

• The angle of incidence equals the angle of refraction

• The incident and reflected rays are perpendicular to each other

Which type of mirror produces a real, inverted image?

• Convex mirror

• Concave mirror (when object is inside the focal point

• Plane mirror

• Concave mirror (when object is outside the focal point)

What happens to light rays when they reflect from a convex mirror?

• • They pass through the focal point

• They converge at a point.

• They diverge, creating a virtual image

• They form a real, inverted image

What is the effect of a convex lens on parallel rays of light?

• It focuses the rays to a point

• What is the effect of a convex lens on parallel rays of light?

• It leaves the rays unaffected

• It scatters the rays in all directions

It scatters the rays in all directions

• They focus parallel rays to a point

• They diverge light rays

• • hey produce only real images

• They produce only real images

The focal point of a concave lens is located:

• On the same side as the object

• At infinity

• • On the opposite side of the object

• At the lens surface

Which type of image is always formed by a concave mirror when the object is located between the focal point and the mirror?

• eal and upright

• Real and inverted

• Virtual and upright

• Virtual and inverted

If the object distance is greater than twice the focal length for a concave lens, what type of image is formed?

• Real and magnified

• Virtual and diminished

• • Real and inverted

• Virtual and magnified

When an object is placed at the focal point of a concave mirror, the image formed is

• Virtual, inverted, and diminished

• Virtual, upright, and at infinity

• Real, upright, and diminished

• Real, inverted, and at infinity
