Which behavior of Convex and Concave Lens is correct?

• Convex Lens diverge the Light. Concave Lens converge the light.

• Convex Lens diverge the Light. Concave Lens diverge the light.

• Convex Lens converge the Light. Concave Lens converge the light.

• Convex Lens converge the Light. Concave Lens diverge the light.

Diagram shows light rays passing through both types of Lenses. What is the point that labelled with F?

• Focal Point

• Focal Length

• Object Distance

• Image Distance

An object is placed in front of a convex lens woth focal length,f. An image of the same size as object is formed on the screen. The object distance is

• Less than f

• Between f and 2f

• Same as 2f

• Greater than 2f

What does it mean when the calculation of linear magnification, m is smaller than 1?

• Image can't be seen

• Image diminished

• Image at the same size with an object

• Image magnified

Which of the following is correct for the image Image characteristic formed by concave lens?

• Virtual, Upright, Magnified.

• Virtual, Upright, Diminished.

• Real, Inverted, Diminished.

• Real, Inverted, Magnified.

For Convex Lens, what is the object distance,u needed in order to produce virtual image?

• u = 2f

• u > 2f

• u > f

• u =< f

In which position of object distance,u will results in Image at Infinity?

• u = f

• u =< f

• u => f

• u = 2f

Concave Lens also known as

• Concaving Lens

• Converging Lens

• Convexing Lens

• Diverging Lens

Diagram shows a type of a lens. What is the name of this type of lens?

• Oval Lens

• Convex Lens

• Concave Lens

• Curved Lens
