For a flat mirror (front surface) with the object having an angle of incidence with the mirror of 45 degrees, and the image measured perpendicular to the object, the speed is v.

A side note, using a laser pointer, a spinning mirror, a meter stick, a ruler, and a sheet of paper, and measured, with a lab partner, the speed of light within 10%, in the space of a square meter. This was so many years ago, that the speed of light was much less than it is today.

Is the distance from the object to the mirror is less than the apparent from the image?

The distance from the object to the mirror is equal to the distance from the image to the mirror in a plane mirror. The image appears to be as far behind the mirror as the object is in front of it, so the apparent distance from the image to the mirror is equal to the actual distance from the object to the mirror.


What image will be produced when an object placed in front of a Plane mirror?

The image produced by a plane mirror will be virtual, upright, and the same size as the object. It will appear to be the same distance behind the mirror as the object is in front of it.


Where does your image appear to be when you look into a plane mirror?

It's a virtual reflection of the object which appears as an image as much behind the mirror as the distance of the object in front.


What is the nature of the image formed by a convex mirror when an object is placed in front of it?

The image formed by a convex mirror when an object is placed in front of it is virtual, upright, and smaller in size than the object.


What is the object image distance relationship for a flat mirror?

when dealing with a flat mirror object-distance and image-distance should be equal.


An object 5 millimeter high is located 15 millimeters in front pf a plane mirror How far from the mirror is the image located?

The image of the object in a plane mirror is located at the same distance behind the mirror as the object is in front of it. Therefore, the image of the object would be located 15 millimeters behind the mirror.


Images formed by a plane mirror?

A plane mirror forms 1 virtual image and no real image. The virtual image is behind the mirror, at the same distance as the object in front of the mirror, erect, in mirror image left-right.


What type of image is produced by the mirror?

The mirror produces a virtual image, which means it appears to be behind the mirror at the same distance as the object in front of the mirror. This virtual image is upright and the same size as the object.


What type of image does a flat mirror produce?

A flat mirror produces a virtual image that is upright, the same size as the object, and with the same orientation as the object. The image appears to be located behind the mirror at the same distance as the object is in front of the mirror.


Where should you place an object on the principal axis in front of a convex mirror to get a virtual upright and smaller image?

To get a virtual upright and smaller image from a convex mirror, place the object in front of the mirror but between its focal point and the mirror. This will produce a virtual image on the same side as the object that is upright and smaller than the object.


An object is 5 millimeters high is located 15 millimeters in front of a plane mirror how far from the mirror is the image located?

The image will be located the same distance behind the mirror as the object is in front of it, so the image will be 15 millimeters behind the mirror.


How image is formed by a plane mirror?

A plane mirror forms an image that is virtual, upright, and laterally inverted compared to the object. The image is located the same distance behind the mirror as the object is in front of it. The size of the image is equal to the size of the object.
