QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Spherical Mirrors.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
A 2 cm tall object is placed 10 cm in front of a concave mirror with a focal length of 5 cm. Calculate the height of the image.
A concave mirror has a focal length of 15 cm. An object is placed 30 cm in front of the mirror. Calculate the image distance.
A concave mirror has a focal length of 20 cm. An object is placed 60 cm from the mirror. Find the position and nature of the image.
A convex mirror has a focal length of 12 cm. An object is placed 24 cm in front of the mirror. Calculate the image distance.
A dentist uses a concave mirror of focal length 4 cm to examine a tooth. If the tooth is 3 cm from the mirror, what is the nature of the image?
A spherical mirror forms an image that is virtual, erect, and larger than the object. What type of mirror is it and where is the object placed?
A spherical mirror forms an image with a magnification of -2. What does the negative sign indicate?
Describe the nature and position of the image formed by a concave mirror when the object is placed between the center of curvature and the focus.
Explain why a convex mirror cannot form a real image of an object placed in front of it.
If an object is placed at the center of curvature of a concave mirror, where will the image be formed?
If the focal length of a convex mirror is 10 cm, what is the radius of curvature?
If the magnification produced by a mirror is +0.5, what can you say about the image?
If the object is placed at the focus of a concave mirror, what is the nature of the image formed?
State the sign convention for measuring distances in the mirror formula for spherical mirrors.
The center of curvature of a spherical mirror is located at a distance of 20 cm from its pole. What is the focal length of the mirror?
The focal length of a concave mirror is -10 cm. An object is placed 15 cm in front of the mirror. Calculate the image distance.
The image formed by a concave mirror is real, inverted, and smaller than the object. Where is the object placed?
The mirror equation is given by 1/f = 1/v + 1/u. What do the symbols v and u represent?
