Spherical Mirrors starts at 9 and continues till grade 12.
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 9
A student places an object 10 cm in front of a concave mirror of focal length 15 cm. Where will the image be formed?
Define the principal axis of a spherical mirror.
Describe the image formed by a concave mirror when the object is placed at the focus.
Describe the nature of the image formed by a convex mirror for any position of the object.
Explain the term 'aperture' in the context of spherical mirrors.
Explain why a concave mirror can be used to concentrate sunlight to a point.
A concave mirror forms an image twice the size of the object. If the object is placed 15 cm from the mirror, what is the image distance?
A student places an object 10 cm in front of a concave mirror of focal length 15 cm. Where will the image be formed?
A convex mirror is preferred as a rear-view mirror because:
(1) It forms a real image
(2) It forms a virtual, diminished image
(3) It forms an enlarged image
(4) It forms an inverted image
If an object is placed between the pole and the focus of a concave mirror, the image formed is:
(1) Real and inverted
(2) Virtual and erect
(3) Real and erect
(4) Virtual and inverted
The relation between the radius of curvature (R) and focal length (f) of a spherical mirror is:
(1) f = R
(2) f = R/2
(3) f = 2R
(4) f = R/3
Which of the following is a type of spherical mirror?
(1) Plane mirror
(2) Convex mirror
(3) Concave mirror
(4) Both 2 and 3
A convex mirror always forms a _______ and _______ image.
A dentist uses a _______ mirror to examine a patient’s teeth.
The center of the sphere of which the mirror is a part is called the _______.
The distance between the pole and the center of curvature is called the _______.
True or False: A concave mirror always forms a real image.
True or False: The focal length of a convex mirror is considered positive.
True or False: The image formed by a concave mirror can be larger than the object.
True or False: The image formed by a convex mirror is always smaller than the object.
