Question

ii) Real image and virtual image​

Answer 1

Answer:

Real images :

A real image is the collection of focus points actually made by converging rays .

• These are produced by intersecting rays .
• Real images can be projected on screen .
• A real image occurs where rays converge .

Example : Picture on Cinema Screen .

Virtual Images :

A Virtual image is the collection of focus points made by extensions of diverging rays .

• virtual image occurs where rays only appear to diverge.
• It is the reflection in mirror.
• Virtual Images are produced by diverging rays .
• These are can't projected on screen.

Example : Reflection in Mirror.

Answer 2

Real image

• Converging rays create a genuine picture, which is made up of a collection of focal points.
• Intersecting rays create this effect.
• On-screen projections of real pictures are possible.
• When rays merge, a genuine picture appears.
• Picture on a Movie Screen, for example.

virtual image​

• The collection of focus points created by the extensions of diverging rays is known as a virtual picture.
• When rays merely seem to diverge, a virtual picture is created.
• It's the mirror's reflection.
• Diverging rays cause virtual images to appear.
• These cannot be displayed on a screen.
• Reflection in a mirror is an example of a reflection.
