Question

Give me 10 disadvantages of convex mirror

Answer 1

Answer:

Convex mirrors provide the impression that objects are further away than they actually are. This is why the mirrors are marked with the phrase "the things on the mirror are closer than they look."

Explanation:

• Reflecting telescopes have their own set of issues. The mirrors must be cleaned on a regular basis due to their size and the design of an open tube assembly.
• It must be corrected every time it is cleaned, which may be costly. A hazy or distorted image arises from an incorrectly oriented telescope.
• A telescope's mirror can be enormous due to its single reflective surface, but it is also exposed to the air. Mirrors covered with a silver surface, which tarnished in the open air, were originally employed in reflecting telescopes.
• To maintain these telescopes clear, they needed to be polished on a regular basis. Mirrors in reflecting telescopes are now covered with aluminium, which oxidises as well but is clear and requires less polishing.
• Even with contemporary telescopes, the reflecting surface's metal coating has to be renewed after years of use.
