What else can I help you with?
A bus driver looks into a plane mirror 20 cm long which is placed 50 cm in front of him if the rear window is 500cm away from the plane mirror through what length of the rear window can he see whene?
The image distance in the mirror is equal to the object distance, and so the total distance the bus driver can see in the mirror is the sum of the object and image distances. Therefore, he can see a total of 110 cm (50 cm from the mirror to his face + 50 cm image distance + 10 cm remaining distance to the rear window) of the rear window through the mirror.
Did a plane mirror always form a virtual image?
No, modern aircraft do not have mirrors. With the exception of fighter aircraft which have them for tactical purposes. The general reason being 90% of airplanes cannot move in reverse. The Airbus A-380 does have a rear viewing camera due to its supreme size. in the bathroom.
Why do you prefer convex mirror as a real veiw mirror in the vehicles?
It gives an erect image and as the image is dimished it would cover a wide range. Though the image is virtual it could be seen by human eyes. Because of all these we use convex mirror as a rear view mirror in vehicles.
What is the different between concave and convex mirror light?
Concave mirror would have the surface curved out get coated with mercury hence curved in surface would reflect the rays fallen on. But convex mirror would have the surface curved in get coated with mercury hence curved out surface would reflect the rays fallen on. Concave mirror would have both converging and diverging ability. When light coming from an object placed at a distance higher than its focal length right from the pole of the mirror, converging takes place. But the object lies in between pole and the focus diverging action. But in convex mirror irrespective of the placement of the object only diverging phenomenon. Concave mirror used as shaving mirror and dentists too use them Convex mirror is used as rear view mirror in case of vehicles near by the driver.
Differentiate between concave and convex mirror?
The outer curved part is coated with mercury as the inner would reflect light in case of concave mirror. Whereas the inner is coated as to make the outer to act as reflector in case of convex mirror. Concave mirror can give both real and virtual images for a real object depending on the location of object. But convex on the other hand can give only virtual image with a real object irrespective of the position of the object. Next, concave mirror can be used as shaving mirror. Also used to converge the parallel beam of light. Convex mirror is best used as rear view mirror in case of vehicles.
How would you compare the images formed in the plane mirror to a rear view mirror of a Car?
In a plane mirror, the image size is of same size as that of the object, but in the rear view mirror, the image size is smaller than that of the mirror.
Which mirror is used as rear view in vechicles?
It's a slightly convex mirror - so that images are magnified a little (making them seem closer than they are)
Why the image formed in the mirror used in vehicles as rear view mirror is smaller in size than the object?
because the mirror used is concave mirror.
How do rear view mirrors work?
Like any other mirror-they just reflect objects.
Why do objects in the rear view mirror appear closer than they are?
The light from an object falls on the mirror. If these rays were to be extended backwards then they would meet behind the mirror making the image also at the back of the mirror. We can't catch this image on the screen. The image looks smaller due to one of the laws of depth perception. This makes the image look even smaller.
Is a rear view mirror convex?
Yes. In convex mirrors, the image is always erect and diminished, at whatever distance the object may be in front of the mirror. The convex mirror has a wide field of view and hence is used as a rear view( or driving) mirror in vehicles, to view the traffic behind.

Where does the small sring hook up on the rear brake kit of a 1999 tracker?
look at the other side, it will be a mirror image
When you drive a car a night and look in your rear view mirror you can see the cars behind you but also when you dip the mirror you can still see a faint image of this why dont you see the back seats?
because it is at the height equal to the rear window and you cn see the back seats if you adjust the mirror
How do you write rear view mirror?
Rear view mirror.

What is an example of a convex mirror?
A plane mirror is a mirror with a planar reflective surface. For light rays striking a plane mirror, the angle of reflection equals the angle of incidence. Thus a collimated beam of light does not spread out after reflection from a plane mirror, except for diffraction effects.Insertformulahere==Images== A plane mirror makes images of objects in front of it; these images appear to be behind the plane in which the mirror lies. A straight line drawn from part of an object to the corresponding part of its image makes a right angle with, and is bisected by, the surface of the plane mirror. The image formed by Insertformulahere==Images==a plane mirror is always virtual (meaning that the light rays do not actually come from the image), upright, and of the same shape and size as the object it is reflecting. A virtual image is a copy of an object formed at the location from which the light rays appear to come. However, the image is a laterally-inverted "mirror image" of the object. If a person is reflected in a plane mirror, the image of his right hand appears to be the left hand of the image.
