    A> An object of height 5 cm is placed 30 cm in front of spherical concave mirror. If the image is real and 10 cm high, what is the radius of curvature of the mirror?

    B> Two lenses, both placed on the x-axis. The first lens is a diverging lens with focal length 4cm placed at x = -2cm. The second lens is a converging lens with focal length 7cm placed at x = 8cm. If an object is placed at x = -18cm, what is the position of the image on the x-axis? (Find the answer to the nearest centimeter)

    In the above problem, which of the following characterizes the final image when compared to the original object?

    A> An object of height 5 cm is placed 30 cm in front of spherical concave mirror. If the image is real and 10 cm high, what is the radius of curvature of the mirror?

    Answer=40cm?

    Mirror formula:

    Where R is negative since it is a concave mirror.

    For concave mirror, the image in this case is inverted, so is negative.

    is positive due to the real image.

    According to the mirror formula:

    The radius of the curvature of the mirror ...

    Solution Summary

    It shows how to find out the images of a spherical concave mirror and a double lenses system, respectively. The solution is detailed and well presented.
