QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Image Formation by 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 11
Describe the difference between real and virtual images.
Describe the image formed by a convex mirror when the object is at infinity.
Explain the term 'lateral inversion' as it relates to images formed by plane mirrors.
Explain why a concave mirror can be used as a shaving mirror.
A concave mirror forms a real, inverted image of an object placed 30 cm from the mirror. The image is formed 60 cm from the mirror. What is the focal length of the mirror?
A concave mirror has a focal length of 10 cm. Where should an object be placed to obtain an image of the same size as the object?
A convex mirror has a focal length of 15 cm. An object is placed 30 cm in front of the mirror. Where is the image formed?
