Multiple choice physics reflection of light and shadow terms related with reflection terms related to reflection of light laws of reflection

When a beam of light, from an object, appears to meet at a point after reflection from a mirror, then the image formed is known as :

  1. real image

  2. virtual image

  3. incident image

  4. all of the above

B Correct answer
Explanation

According to definition, when a beam of light appears to meet at a point, after reflection, from a mirror then the image formed is known as virtual image. It cannot be obtained on a screen.

One feature of image formed by plane mirrors is lateral inversion which means:

  1. the top part of the image appears downward and vice versa

  2. left and right sides of the image are interchanged

  3. image appears inverted both sideways and upside down

  4. all the above

B Correct answer
Explanation

When a mirror forms an image, the left and right sides of the image are interchanged. This phenomenon is called lateral inversion as the image is laterally inverted.

Multiple choice physics reflection of light and shadow terms related with reflection terms related to reflection of light laws of reflection

No matter how far you stand from a mirror, your image always appears erect. Then the mirror among the following is likely to be:

  1. a plane mirror

  2. a concave mirror

  3. any type of mirror

  4. none of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

If the image always appears erect, then the mirror is either plane or convex. So, on the basis of the given options, the mirror is likely to be a plane mirror.

Fill in the blanks to complete the following sentences:


i) A ray travelling towards the mirror is the ______.
ii) Angle between reflected ray and normal is the ___.
iii) The angle between reflecting surface and the reflected ray is the ______.

  1. i-incident ray ,ii-angle of reflection ,iii-glancing angle of reflection

  2. i-normal ray ,ii-glancing angle of reflection ,iii-angle of incidence

  3. i-reflected ray ,ii glancing angle of incidence ,iii-glancing angle of reflection

  4. i-reflected ray ,ii-angle of incidence ,iii- angle of reflection
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

According to definition, 
i) A ray from the object, travelling towards the mirror is the incident ray.
ii) Angle between reflected ray and normal is the angle of reflection.
iii) The angle between reflecting surface and the reflected ray is known as the glancing angle of reflection.

The ray which bounces off the surface of the mirror when the incident ray strikes the mirror is known as ________.  The point at which incident ray meets the mirror is called the _________.

  1. normal ray, point of reflection

  2. reflected ray, point of refraction

  3. reflected ray, point of incidence

  4. diffracted ray, point of diffraction
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

According to definition of reflected ray and point of incidence, the ray which bounces off the surface of the mirror when the incident ray strikes the mirror is known as the reflected ray. The point at which incident ray meets the mirror is called the point of incidence.
