Exploration 34.1: Lens and a Changing Index of Refraction
Please wait for the animation to completely load.
Light rays from a point source, initially in air, are shown incident on a lens. Restart.
- How, if at all, would the path of the rays change if the source and lens were placed in another medium with an index of refraction of n = 1.2, which is less than the index of refraction of the lens? Make a prediction and then test your prediction by using the slider to increase the index of refraction of the surrounding medium.
- Now, what would happen if the index is increased to n = 2.0, so that it exceeds the index of refraction for the lens? Make a prediction and then check your prediction using the slider.
