Important Questions on Light – Reflection and Refraction
For the diagram shown, according to the new Cartesian sign convention the magnification of the image formed will have the following specifications.
An object of height is kept at a distance of from the pole of a diverging mirror. If the focal length of the mirror is , the height of the image formed is ____.
Observe the following diagram and answer the question given below
Explain why a ray of light passing through the centre of curvature of a concave mirror gets reflected back along the same path.
A student holding a mirror in his hand, directed the reflecting surface of the mirror towards the Sun. He then directed the reflected light on to a sheet of paper held close to the mirror.
Which type of mirror does he have?
Which of the following statements is not true in reference to the diagram shown above?
Draw a Ray diagram to show the formation of an image when the object is placed between the pole and the focus of a Concave Mirror.
The radius of curvature of a converging mirror is . At what distance from the mirror should an object be placed so as to obtain a virtual image?
Draw a ray diagram to show the formation of an image when an object is placed between and of a concave mirror.
What should he do to burn the paper?
A concave mirror produces times enlarged image of an object placed in front of it. Calculate its radius of curvature.
An object is placed at a distance of in front of a Concave Mirror. If an image of its is formed at from the mirror, find the focal length of the mirror.
In which of the following is a concave mirror is used?
A student holding a mirror in his hand, directed the reflecting surface of the mirror towards the Sun. He then directed the reflected light on to a sheet of paper held close to the mirror.
Will he be able to determine the approximate value of focal length of this mirror from this activity ? Give reason and draw ray diagram to justify your answer in this case.
