A concave mirror and a convex lens are held in waterwhat changes if any do you expect in their focal length?
Kishansarraf
Excellent question.
The answer is actually yes!
According to the lens makers formula, it will change based on the refractive index of the material of the concave mirror wrt the medium.
Google Lens makers formula for better understanding!
NO! the focal length of the mirror will not change if it would be a lens then the focal length would change. The lens maker's formula is for Lenses only!

How does temperature affect metals?
Temperature affects metals in several ways:they expand with increasing temperaturetheir electrical resistance changes - we expect their resistance to increase with increasing temperaturetheir mechanical properties (such as ductility, hardness. tensile strength, yeild stress, etc) change - for example usually becoming softer and more ductile with increasing temperaturesome metals will undergo solid state phase changes with changes in temperature - especially alloys
