WebA 4.0-cm tall light bulb is placed a distance of 8.3 cm from a concave mirror having a focal length of 15.2 cm. (NOTE: this is the same object and the same mirror, only this time the object is placed closer to the mirror.) Determine the image distance and the image size. Again, begin by the identification of the known information. WebThe focal length will increase because the water will cause more bending of light. The focal length stays the same because it depends on the fact that the angle of incidence is equal to the angle of reflection for a mirror. This is unaffected by the presence of the water. Water will refract the light. This, combined with the reflection due to ...

WebIn case of spherical mirrors (both concave and convex), there will be no change in the focal length of the mirrors when immersed in water. This is because the focal length of mirrors does not depend on the external medium in which it is held. In case of lenses, refraction takes place. When a lens is immersed in water, the value of refractive ... WebWhat happens to the focal length of convex lens when it is immersed in water? Refractive index of the material of lens is greater than that of water. What will happen to the focal … perry v sindermann case brief
If a spherical mirror is immersed in water, does its focal length ...
WebAccording to our science textbook focal length(f) of a mirror/ lens is equal to half its radius of curvature(R).Which means that there is a specific focal length for a given lens/mirror(f=R/2). WebThe focal lengths of a mirror does not depend upon the nature of the medium in which it is placed whereas the focal length of a lens depends upon the medium in which it is placed. Thus there will be no change in the focal length of the concave mirror whereas the focal length of the convex lens will change. WebDec 9, 2004 · Also, this is the reason your eyes cannot focus under water. To be 100% exact, "No" should read: "no when using front coated mirrors". In your every day life, mirrors have a reflective layer at the back of a piece of glass. Just to make sure the cleaning lady doesn't scratch it off. Using such a mirror would change the focal length, … perry v. united states
