2. (a) (b) A spherical concave mirror has a radius of curvature of 65 cm. An object is placed 40 cm to the left of the mirror. Calculate the image position and its magnification. Sketch a ray diagram clearly illustrating if the image is real or inverted. (6 marks) (i) Define the term critical angle for a light rav nassing from a material with a larger.

The power for normal distant vision is 50.0 D. A severely myopic patient has a far point of 5.00 cm. By how many diopters should the power of his eye be reduced in laser vision correction to obtain normal distant vision for him?

Exp1ain why an object in water always appears to be at a depth shallower than it actually is?

Suppose a man stands in front of a mm-or as show below. His eyes are 1.65 m above the floor and the top of his head is 0.13 m higher. Find the height above the floor of the top and bottom of the smallest minor in which he can see both the top of his head and his feet. How is this distance related to the man’s height?

A prism that has an apex angle of 50.0 is made of cubic zirconia. What is its minimum angle of deviation?

The headlights of a car are 1.3 m apart. What is the maximum distance at which the eye can resolve these two headlights? Take the pupil diameter to be 0.40 cm.

A 7.5x binocular produces an angular magnification of 7.50, acting like a telescope. (Mirrors are used to make the image upright.) If the binoculars have objective lenses with a 75.0 cm focal length, what is the focal length of the eyepiece lenses?

The power for normal close vision is 54.0 D. In a vision-correction procedure, the power of a patient’s eye is increased by 3.00 D. Assuming that this produces normal close vision, what was the patient’s near point before the procedure?

The projection lens in a certain slide projector is a single thin lens. A slide 24.0 mm high is to be projected so that its image fills a screen 1.80 m high. The slide-to-screen distance is 3.00 m. (a) Determine the local length of the projection lens, (b) How far from the slide should the lens of the projector be placed so as to form the image on the screen?

A student’s eyes, while reading the blackboard, have a power of 51.0 D. How far is the board from his eyes?
