A beam of converging rays is incident on a convex mirror of radius of curvature 30 cm and after reflection meet at a distance of 10 cm in front of the mirror. Where in absence of the mirror would the converiging rays meet? (in cm)
The focal-length of a spherical mirror of radius of curvature 20cm is
A beam of converging rays is incident on a convex mirror of focal length 30cm. In the absence of the mirror the converging rays would meet at a distance of 20cm from the pole of the mirror. If the mirror is situated at the said position where will the converging rays meet?
If a converging beam of light is incident on a concave mirror, the reflected light
A converging beam of rays meets at a point 15 cm in front of a convex mirror of radius of curvature 20 cm. In absence of the mirror where would the beam of rays meet?
An object is placed in front of a convex mirror of radius or curvature 20cm. Its image is formed 8cm behind the mirror. Find the distance of object from the image.
A ray of light is incident on a concave mirror along its principal axis.What will be the angle of reflection?
A concave mirror of radius of curvature 20 cm and a convex mirror of radius of curvature 30 cm are held coaxially face to face at a distance of 40 cm apart. An object of height 5 cm is placed perpendicularly on the common axis at a distance of 15 cm from the concave mirror. The height of the final image will be
A concave mirror of radius of curvature 20 cm and a convex mirror of radius of curvature 30 cm are held coaxially face to face at a distance of 40 cm apart. An object of height 5 cm is placed perpendicularly on the common axis at a distance of 15 cm from the concave mirror. If the first reflection occurs in the concave mirror, the final image will be formed at a distance of
An object is placed perpendicularly on the principal axis of a concave mirror of focal length 25 cm and an image is formed at a distance of 100 cm in front of the mirror. Determine the position of the object and mangnification of the image.
