A glass rod seems to disappear when it is placed in vegetable oil. Based on this observation, predict the index of refraction for vegetable oil.
The index of refraction for vegetable oil is predicted to be similar to that of glass, based on the observation that a glass rod appears to disappear when submerged in vegetable oil. This phenomenon occurs due to the matching refractive indices, which minimizes light refraction at the interface. Consequently, the visual effect of the glass rod vanishing is a direct result of this optical property.
