Question
If a spherical mirror is immersed in water, does its focal length change? Explain
Step-by-Step Solution
Verified Answer
No spherical mirror it will remain the same, it will not change.
1Step1: Focal point
Focal point is the plane perpendicular to the axis of a lens or mirror and that passes through the focus of the mirror.
2Step2: Answer explanation
The focal length of the mirror follows from the curvature of the mirror and the laws of reflection. The laws of reflection are independent of the wavelength of the light and the focal length doesn’t change when the mirror is immersed in water.
