34.14 For a convex spherical mirror that has focal length f=-12cm, what is the distance of an object from the mirror’s vertex if the height of the image is half the height of the object?

A concave mirror has a radius of curvature of 34.0cm. (a) What is its focal length? (b) If the mirror is immersed in water (refractive index 1.33), what is its focal length?

The focal length is independent of the medium in which it is immersed. So, the focal length will stay same in water, that is, f=17cm.

If the monochromatic light shown in Fig. 35.5a were replaced by white light, would a two-slit interference pattern be seen on the screen? Explain.

The radius of curvature of concave mirror is always positive, therefore, the same is for the focal length. The radius is twice of the focal length.

Could the Young two-slit interference experiment be performed with gamma rays? If not, why not? If so, discuss differences in the experimental design compared to the experiment with visible light.
