Question

The focal length of concave mirror is safe is there any change in focal length when it is completely immersed in water if not why ​

Answer 1

When the mirror is totally immersed in water or liquid then the focal length of mirror is not changed because focal length is the half of radius of curvature .when the mirror is partially immersed in water then the focal length of mirror is changed due to refraction of light from one medium to another

Answer 2

$<b>Hello Friend<b>$ ❤️❤️

The answer of u r question is..✌️✌️

The focal length of a concave mirror is if is there any change in focal length when it is completely immersed in water if not why ?

Ans:✍️✍️✍️✍️✍️✍️✍️

As there is no change in medium then there is no change in focal length the incident angle and reflected angle are same as both Resort travelling in same medium example water therefore focal length is independent medium .

Hope it helps uu buddy!!❤️❤️

Thank you..☺️☺️
