FAQs on Differentiate between Real image and Virtual image.Light : Reflection and Refraction Video Lecture - Class 7

1. What is a real image?
Ans. A real image is formed by the actual intersection of light rays. It is formed when light rays converge at a point after passing through a lens or reflecting off a mirror. The real image can be captured on a screen or a film and is always inverted.
2. What is a virtual image?
Ans. A virtual image is formed by the apparent intersection of light rays. It is formed when light rays appear to converge at a point but do not actually intersect. Virtual images cannot be captured on a screen or a film and are always upright.
3. How is a real image formed?
Ans. A real image is formed when light rays pass through a converging lens or reflect off a concave mirror. The light rays converge at a point on the opposite side of the lens or mirror, forming an inverted image. The distance of the real image from the lens or mirror depends on the position of the object.
4. How is a virtual image formed?
Ans. A virtual image is formed when light rays diverge after passing through a diverging lens or reflect off a convex mirror. The light rays appear to converge at a point on the same side as the object, forming an upright image. The distance of the virtual image from the lens or mirror is always negative.
5. Can a real image be projected onto a screen?
Ans. Yes, a real image can be projected onto a screen. Since a real image is formed by the actual intersection of light rays, it can be captured and projected onto a screen or a film. This is commonly seen in movie projectors and cameras.
