Question
the focal length of the mirror? A child holds a candy bar 15.3 cm in front the convex side-view mirror of an automobile. The image height is reduced by one fifth. What is the radius of curvature of A ray of light traveling in air striker the point of one face of an equiangular glass prison (n = 1.5) at an angle of exactly 30.0 degree. A convex spherical mirror has a radius of curvature of 35 cm. The object distance is 19.5 cm. Trace the path of the light ray through the glass and find the angle of incidence of the ray at the bottom of the prism. Calculate the critical angle corresponding to total internal reflection. Find the magnitude of the image distance. Find the magnification. The real image produced by a concave mirror is found to be 0.504 times the size of the object. If the distance from the mirror to the screen on which the image appears is 1.23 m, what isExplanation / Answer
m = hi/ho = 1.504
do = -di/m =-1.23/1.504 = -0.82 m [The -ve values for image height indicate that the image is an inverted image.]
Now 1 /do + 1/di = 1/f
1/ 0.82 + 1/1.23 = 1/f
f = 0.492 m
