Free Physics animation - See this full physics animation in preview : Why do we use a convex mirror in rear view mirror, what will happen if we use a plain mirror instead. This animated physics topic gives in-depth information about rear view mirror.

 |
|
How a rear view mirror, used in
a car, ensures safety
|
A plane mirror used has a lower
range as compared to the convex mirror
|
|
Rear view mirrors of cars are
also convex mirrors as they enable the driver to see a wide
area of the road behind the car.
The convex mirror makes the rays of a parallel beam diverge
as if they were coming from its focus, thereby producing
a diminished virtual image, which the driver can see.
Convex mirrors reflect rays outwards: the rays coming from
a convex mirror appear to come from a single point behind
the mirror.
An image is formed behind the mirror and is smaller than
the object. Convex mirrors can capture rays from a wide
area.
Comparison between a plane mirror and a convex mirror would
show that the field of view in the case of the convex mirror
is much wider than a plane mirror.
If you are still unclear about the concepts, please refer

| Ans: |
Many teachers discourage asking of questions and worse make wisecracks in place of answers. This turns lot of students off from fulfilling their curiosity and learning becomes a chore. To solve numerical take up first the easy one and do not, repeat do not give up until you have solved it, slowly tackle tougher ones and till you become confident. Remember efforts fail, person doesn’t. So, move forward in a step-by-step manner. One can build an empire if one places a brick at a time. |
| Q4: |
we represent WORWDONE in (n-m) OR (J);BUT we dont represent moment in "joules",why? |

| Ans: |
Torque is a measure of force acting on an object to cause that object to rotate. However, torque is not energy. Torque or moment is vector (pseudo) while work done or energy is scalar, energy can be represented by both force dot distance (N.m) and joules in SI units but torque is the cross product between the distance vector and the force vector, hence it can only be expressed in N.m |
| Q5: |

| Ans: |
Water vapour is not wet it is the vapour or gaseous state of water, steam may contain droplets of liquid water, Please ask the question in correct section |
