4. The type of lens used as a magnifying glass(a)Concave lens(b) Convex lens(c)Concavo-convex lens(d) Convexo-concave lens

What is another name for a convex lens?A concave lensA converging lensA diverging lensA negative lens2What will happen to parallel rays of light which strike a convex lens?They will converge upon exiting the lensThey will still be parallel upon exiting the lensThey will diverge upon exiting the lensIt is impossible to say without knowing the exact shape of the lens3What will happen to parallel rays of light which strike a concave lens?They will diverge upon exiting the lensThey will converge upon exiting the lensThey will still be parallel upon exiting the lensIt is impossible to say without knowing the exact shape of the lens4A convex lens has a focal length of 30 cm.  In which of the following cases will a real image NOT be produced?When an object is placed 80 cm from the lensWhen an object is placed 60 cm from the lensWhen an object is placed 20 cm from the lensWhen an object is placed 40 cm from the lens5The focal length of a convex lens is 10 cm.  An object is placed 15 cm from the lens.  Which of the following describes the image which will be produced of this object?Real, inverted and diminishedReal, inverted and magnifiedVirtual, inverted and diminishedVirtual, upright and magnified6Lenses work as a result of which of the following processes?ReflectionRarefactionReflationRefraction

Magnification (m) provided by a convex mirror can be

7. You are provided with a convex mirror, a concave mirror, aconvex lens and a concave lens. You can get an inverted imagefrom(a) both concave lens and convex lens.(b) both concave mirror and convex mirror.(c) both concave mirror and convex lens.(d) both convex mirror and concave lens

Under which conditions concave mirrors form an image larger than the actual object?*1 pointWhen an object is kept at a distance less than its focal length.When an object is kept at a distance equal to its radius of curvature.When an object is placed between the focus and center of curvature.When an object is kept at a distance greater than its radius of curvature.
