What is the delay time of a mirror?

Light moves at about one foot per nanosecond so if you see someone 5 feet away from you, your image is five nanoseconds late. If you look at something in a mirror, there is time for light to get from the object to the mirror and then to get from the mirror to your eyes.

How long does a mirror need to be to see yourself?

In other words, to view an image of yourself in a plane mirror, you will need an amount of mirror equal to one-half of your height. A 6-foot tall man needs 3-feet of mirror (positioned properly) in order to view his entire image.

How far behind a plane mirror does your reflection appear?

Object Distance and Image Distance That is the image is the same distance behind the mirror as the object is in front of the mirror. If you stand a distance of 2 meters from a plane mirror, you must focus at a location 2 meters behind the mirror in order to view your image.

How far can Mirrors reflect light?

A very complex dielectric mirror can reflect up to 99.999\% of the light incident upon it, for a narrow range of wavelengths and angles. A simpler mirror may reflect 99.9\% of the light, but may cover a broader range of wavelengths.

Can a reflection be delayed?

Yes, there is a delay between when the light hits an object and when the reflection starts. This is because a reflection isn’t really light “bouncing off” an object.

Are mirrors instant?

when light encounters a mirror, is it instantly reflected, or is it absorbed very briefly and then emitted? The simple answer is: It is instantly reflected, because the interference at the surface between the incident and reflected wave takes place at the same time for each.

Will you see more or less of your body if you step closer to the mirror?

As long as your image in the mirror fits in your field of vision, You will see the same amount of yourself in the mirror. It is only when you get close enough to the mirror that your image goes beyond your field of vision do you see less of yourself.

Why does a plane mirror image appear to be behind the mirror?

Image in a Plane Mirror Plane mirrors work because the light rays create a virtual image behind the mirror. Light rays from the object strike the mirror and reflect according to the law of reflection.

What is the reference of measuring distances in case of a mirror?

It is represented by the symbol R. Focal length. The distance between the pole and the principal focus of the mirror, is called the focal length of the mirror.

What is a true reflection mirror?

According to its website, “[True Mirror] is formed by taking two special ‘front-surface’ mirrors and joining them at exactly 90 degrees to form a seamless, three-dimensional, non-reversed image.” The result is a mirror shaped like the corner of a room, which inverts your typical reflection (i.e., when you lift your …

How much do mirrors reflect?

Window glass can reflect only eight percent of light hitting it, while mirrors can reflect 95 percent of light hitting them. The glass in a mirror is usually coated with a layer of silver or aluminum.

How far away would you see yourself in the mirror?

2. If you stand three feet in front of a plane mirror, how far away would you see yourself in the mirror? If you stand 3 feet from the mirror, then your image is three feet on the other side of the mirror; this puts your image a total of six feet from you (3 feet to the mirror plus 3 more feet to the image).

How much mirror does a 6-foot man need to view his image?

A 6-foot tall man needs 3-feet of mirror to view his whole image regardless of where he is standing. In fact, the man needs the exact same 3-feet of mirror. A common Physics lab involves using a tall plane mirror to explore the relationship between object height and the portion of mirror needed to view an image.

How far away does a concave mirror create a real image?

A concave mirror with a focal length of 10.0 cm creates a real image 30.0 cm away on its principal axis; the corresponding object is located how far from the mirror? Substitute and solve for d o. Link to More Information About

When you look at your image in a plane mirror?

When you look at your image in a plane mirror, you see an upright image; it is located on the other side of the mirror (and thus is virtual ); finally, it has the same dimensions (height, width) as yourself (the object). Link to More Information About 9.
