Why would you use convex lens to start a fire?
A convex lens can concentrate sunlight to a small point, creating intense heat that can ignite materials. By focusing sunlight through a convex lens onto a combustible material, you can generate enough heat to start a fire. This process is called solar or lens fire starting.
How would you find the focal point of a convex mirror?
To find the focal point of a convex mirror, you can use the formula: f = R/2, where R is the radius of curvature of the mirror. The focal point of a convex mirror is located behind the mirror, at a distance equal to half the radius of curvature.
Does a driving mirror use a concave mirror or convex mirror?
A driving mirror typically uses a convex mirror. Convex mirrors are used because they provide a wider field of view, allowing drivers to see more of their surroundings. This helps with detecting objects in blind spots and improving overall safety while driving.
Why vehicles use plane mirror and convex mirror as rearveiw?
Vehicles use a plane mirror for the central rearview mirror to provide an accurate reflection of objects behind the vehicle. A convex mirror is used as the side mirror to provide a wider field of view and reduce blind spots. This combination helps the driver have a clear view of the surroundings and enhances safety while driving.
What is another name for a convex lens?
Concave and convex can refer the types of lenses used to treat refractive errors in the eyes. Concave is another word for myopic lens and convex is another name for a hyperopic lens also known as nearsighted and farsighted respectively
Does a torch use a concave mirror or convex mirror?
Concave
Can convex mirrors be uses as a shaving mirror?
No, this is because the image formed in convex mirror is smaller and the shape of the image is irregular. So if we use convex mirrors as a shaving mirror, there are chances of getting hurt whle shaving.

Why motorists use convex mirror?
There are convex mirrors found in the form of side view mirrors in all the vehicles because convex mirror has a property that the image formed is smaller than the actual size of the object and hence it allows to see a large area in a small mirror which is useful during driving
