Which type of mirror can form a real image?
Solution: Concave mirrors can form real images. Convex and plane mirrors always form virtual images. Want to top your science exam ?
How important is plane mirror to you?
Plane mirror reflections create upright virtual images at the same magnification, or size, and distance as the objects they reflect. This is why you can use a plane mirror to determine exactly where something behind you is.
What are the application of plane mirror?
Applications and Uses of Mirrors
- Periscopes and kaleidoscopes.
- Automobiles.
- Torch Lights.
- Shaving Mirrors.
- In Dentist.
- Solar Cooker.
- Security.
What are the disadvantages of plane mirror?
What is its drawback? The image size is smaller than the object size, the objects in the mirror appear to be farther than they actually are. This can cause the viewer to assume the car behind him might be farther than it is.
Can a plane mirror ever form a real image?
Plane mirrors are the only type of mirror for which a real object always produces an image that is virtual, erect and of the same size as the object. Virtual objects produce real images, however. The focal length of a plane mirror is infinity; its optical power is zero.
Is the image in a plane mirror laterally inverted?
The image formed by a plane mirror is laterally inverted, upright, of the same size and is formed far behind the mirror as the object is in front of it.
Why is focal length of plane mirror infinity?
The focal length of a plane mirror is infinity as the image can be formed at an infinite distance inside the mirror. Focal length is half of the radius of curvature and hence it is infinity.
How would the letter F appear in front of plane mirror?
Answer. Answer: The images on a plane mirror are laterally inverted i.e if you hold your left hand up your image will show your right hand up.
How will the letter E appear in the mirror?
Answer: it will appear backwards or reversed, facing the wrong direction. Like Ǝ or ɘ. This is because light in the mirror is reflected backwards.
What is lateral inversion give an example?
Lateral inversion is the real or apparent reversal of left and right. For example, the letter b when laterally inverted becomes the letter d (more or less). It is well-known that a plane mirror causes the apparent lateral inversion of objects.
What are the important differences between looking at photograph?
Solution
| Photograph | Image in a Plane Mirror |
|---|---|
| A photograph is made when a real image is projected on a photographic film. | The image formed by a plane mirror is virtual and cannot be taken on a photograph. |
| The image is smaller in size compared to the actual object. | The image is the same size as the object. |
What is main difference between what we see in the two pictures alongside?
Explanation: Main difference is cleanness .
What is the difference between looking at photograph of your face and looking at yourself in a plane mirror?
What are the important differences between looking at a photograph of your face and looking at yourself in a plane mirror ? Solution : A image of our face in a plane mirror is laterally inverted, so left is right and right is left. However, in a photograph of our face this is not the case.
How does photograph differ from your reflection in the mirror?
The rule of reflection is what makes a mirror different from a photograph. A photograph scatters light in all directions, like our bulb. A mirror reflects light that comes in at a particular angle in just one direction, so it can preserve information about distance.
What is the same about you and your mirror image?
The mirror image shows “lateral inversion”. That means you perceive your image as having its left and right sides reversed compared with how you really look. To see how you look to other people, use a second mirror to view your image in the first mirror. Then your left and right will be the same as in a photo.
How do I find my true reflection?
Hold two hand mirrors in front of you with their edges touching and a right angle between them like the two covers of a book when you’re reading. With a little adjustment you can get a complete reflection of your face as others see it. Wink with your right eye. The person in the mirror winks his or her right eye.
When a person sees himself in a mirror What do his eyes observe?
When one looks into a mirror it appears as if you are looking through it and seeing the object on the other side. It also seems as if the object is flipped left to right. In reality the right half of the real object is on the same side as the right half of the virtual object.
Is mirror gazing dangerous?
When you stare at your eyes in the mirror for a long time in a dimly lit room your brain literally gets bored and it tries to scare you. After a while of staring into your eyes you can see your face all warped and creepy.
Is a Selfie how others see you?

Do others see you inverted?
You normally see yourself as a reflection such as in a mirror. This image is actually the reversed or “mirrored” image, not the photo. On the other persons phone seeing the image of you, they see the non-mirrored image which looks normal to them but weird to you.
Which is more accurate mirror or photo?
