Write true or false of the following statement.
The objects are seen around us due to irregular reflection of light.
Fill in the blank
Angle of incidence = ___________
Explain the following terms:
Incident ray, Reflected ray, Angle of incidence, Angle of reflection, Normal.
In the following diagrams, measure and write the angle of incidence and draw the reflected ray in a given case.
State in words, how do you find the location of image of an object formed by a plane mirror.
Draw a ray diagram showing the formation of image of a point object by a plane mirror.
Define the following term
Reflected ray
The angle between incident ray and reflected ray is 60°. What is the value of angle of incidence?
Draw figure showing the position of the plane mirror. Also, label the angle of incidence and angle of reflection on it.
Assertion (A): A ray incident along normal to the mirror retraces its path.
Reason (R): In reflection, the angle of incidence is always equal to the angle of reflection.
