A particular patient's eyes are unable to focus on objects closer than 36.5 cm and corrected lenses are to be prescribed so that the patient can focus on objects 21.0 cm from their eyes. If contact lenses are to be prescribed, determine the required lens power (in diopters).If eyeglasses are to be prescribed instead and the distance between the eyes and the lenses is 1.90 cm, determine the power (in diopters) of the required corrective lenses.

What power of spectacle lens is needed to correct the vision of a nearsighted person whose far point is 30.0cm. Assume the spectacle lens is held 1.50cm away from the eye by eyeglass frames.

Light travels from air into an optical fiber with an index of refraction of 1.44. (a) In which direction does the light bend? (b) If the angle of incidence on the end of the fiber is 22^o, what is the angle of refraction inside the fiber? (c) Sketch the path of light as it changes media.

Two convex lenses with focal lengths of 30cm are placed 100cm apart. An object is placed 15cm in front of the first lense. Determine the position and magnification of the final image due to both lenses.

In a young double slit experiment the separation is 0.05cm and the distance between the double slit and screen is 200cm when blue light is used , the distance of the interference pattern is 0.13cm
