Light and Lenses Activity

What type of lens is a convex lens?

• Converging lens

• Diverging lens

• Flat lens

• None of the above

What happens to a ray of light parallel to the principal axis after it passes through a convex lens?

• It reflects back to the source

• It passes through the focus on the other side

• It continues straight without deviation

• It diverges away

What is the nature of the image formed by a convex lens when the object is placed beyond 2F1?

• Real and erect

• Virtual and erect

• Real and inverted

• Virtual and inverted

For a concave lens, where is the image formed regardless of the object's position?

• Beyond 2F2

• Between the object and the lens

• At the optical center

• At infinity

What is the nature of the image formed by a concave lens?

• Real and erect

• Virtual and inverted

• Virtual and erect

• Real and inverted

When an object is placed at 2F1 in front of a convex lens, where is the image formed?

• At 2F2

• At F2

• Between F2 and 2F2

• At infinity

What is the rule for a ray of light passing through the optical center of a lens?

• It reflects back

• It goes straight through without deviation

• It bends towards the focus

• It diverges away

What is the nature of the image formed by a convex lens when the object is placed at the focus?

• Real and inverted

• Virtual and erect

• Real and magnified

• Formed at infinity

What is a practical use of a convex lens with the object placed between the optical center and the focus?

• Camera

• Telescope

• Microscope

• Magnifying glass

What happens to a ray of light that is parallel to the principal axis after passing through a concave lens?

• It continues straight without deviation

• It appears to come from the focus

• It reflects back to the source

• It passes through the focus on the same side
