Summary

In this lesson, Ibu Santi explains the concepts of real and virtual images. Real images are formed by the meeting of reflected or refracted rays and can only be created by concave mirrors and convex lenses. These images are inverted and appear in front of concave mirrors or behind convex lenses. On the other hand, virtual images are formed by the extension of reflected or refracted rays, and they can be produced by flat mirrors, concave mirrors, convex mirrors, and both concave and convex lenses. Virtual images appear upright and can be seen behind mirrors or on the same side as the object with lenses.

Takeaways

• 😀 Real image is formed when reflected or refracted light rays meet.
• 😀 Virtual image is formed by the extension of reflected or refracted light rays.
• 😀 Real images can only be produced by concave mirrors and convex lenses.
• 😀 In concave mirrors, real images are formed in front of the mirror.
• 😀 In convex lenses, real images are formed behind the lens, opposite to the object.
• 😀 Virtual images can be formed by flat mirrors, concave mirrors, convex mirrors, concave lenses, and convex lenses.
• 😀 In flat mirrors, virtual images appear behind the mirror.
• 😀 In lenses, virtual images appear on the same side as the object.
• 😀 Real images are inverted (upside-down).
• 😀 Virtual images are upright (right side up).

Q & A

What is a real image in physics?

A real image is an image formed by the convergence of reflected or refracted light rays. It can only be produced by concave mirrors and convex lenses.

Where is a real image located when formed by a concave mirror?

In a concave mirror, a real image is formed in front of the mirror.

Where is a real image located when formed by a convex lens?

In a convex lens, a real image is formed on the opposite side of the object, behind the lens.

What is a virtual image in physics?

A virtual image is formed by the extension of reflected or refracted rays, and it cannot be projected onto a screen.

Can a virtual image be formed by a flat mirror?

Yes, a virtual image can be formed by a flat mirror, as well as by concave mirrors, convex mirrors, concave lenses, and convex lenses.

Where is a virtual image formed in a flat mirror?

In a flat mirror, the virtual image is formed behind the mirror, appearing as if it is inside the mirror.

What happens to the position of a virtual image in a lens?

In a lens, the virtual image is formed on the same side as the object, and it is upright.

What is the difference between a real image and a virtual image in terms of position?

A real image is inverted and located in a different position relative to the object, while a virtual image is upright and appears on the same side as the object.

Can a concave mirror form a virtual image?

Yes, a concave mirror can form a virtual image, but only under specific conditions, such as when the object is placed closer to the mirror than its focal point.

How does the image produced by a convex lens differ from that produced by a concave mirror?

A convex lens produces a real image that is inverted and formed behind the lens, while a concave mirror produces a real image that is inverted and formed in front of the mirror. Both types of image are formed through convergence of light rays.
