To find the power of the lens with a focal length of -0.25 meters, we use the formula P = 1/f. Substituting the given focal length, we get P = 1/(-0.25), resulting in a power of -4.0 D. This negative ...

A lens with a power of +1.5 D is a convex lens. The positive power implies that the lens converges light. Using the formula P = 1/f, where P is power and f is the focal length, we find that ...

A lens with a power of -3.5 D indicates a concave lens. To find the focal length, we can use the relationship between power (P) and focal length (f), where P = 1/f. Therefore, the focal length would be -0.29 ...

Convex mirrors enable the driver to view a much larger area than would be possible with a plane mirror. The curvature of the convex mirror expands the scope of visibility, providing a broader awareness of the surroundings for safer driving.

Convex mirrors have a wider field of view due to their outward curvature. This wider field of view allows the driver to see more of the surrounding traffic and environment, enhancing safety by minimizing blind spots.
