two different materials —glass and diamond —are used to make convex lenses of the same thickness. we know that diamond can be bend light more than glass.Which lense will have a greater focal length???....
Answers
Answer:
Focal length of glass made lens will be greater, because the focat length depends on radius of curvature of lens. So as the diamond bends more, its radius of curvature is less therefore its focal length is also short. So, the glass lens will have greater focal length.
Explanation:
diamond will bend more light and the light ray will meet at a nearer point as compared to light ray passed through glass lens .
If refractive index of material of lens is more bending of light is more and focal length of lens decreases[ as Focal length is inversely proportional to Refractive index].
As, diamond can refract a light to a more extent, its refractive index is high and focal length is less.
Conclusion:
Glass convex lens has more focal length.
Answer:
Focal length of glass made lense will be greater because the focal length depends on radius of curvature of lense so as the diamond bends more its radius of curvature is less therefore it's focal length is also short so the glass lense will have a greater focal length.
Explanation:
Diamond will bend more light and the light ray will meet at a nearer point as compared to light ray passed through glass lense.
Refractive indexof materials of lense is more bending of light is more and focal of length decrease ( as a focal length inverseble propotion to reactive index).
As diamond can refract a light to a more extent its refractive index us high and focal length is less
Conclusion
Glass convex lens have more focal length
