1) Compute the period of a 0.123-nmX-ray.
2) An object is placed halfway among a concave mirror and its focal point. Discover the resulting magnification.
3) A 3-cm-tall object is located 8 cm in front of a concave mirror that has a 20-cm radius of curvature. Compute the resulting image height.
4) What is the minimum time it will take light to refract during a pane of glass 1 cm thick?
5) A concave mirror has a focal length of 17.0 cm. If it is forming an image 36.0 cm in front of the mirror, what is the magnification?
