I can't see images or visual content directly, but I can help you understand how a light ray behaves as it travels from one medium to another, like from air to oil and water.
When a light ray enters a denser medium (in this case, oil and water), it will bend towards the normal line. The normal line is an imaginary line perpendicular to the surface at the point of incidence.
- From Air to Oil: Since oil is denser than air, the light ray will bend towards the normal as it enters the oil.
- From Oil to Water: Water is denser than oil, and when the light ray travels from oil to water, it will again bend towards the normal.
If you have descriptions of the options that show the light ray's trajectory through the beaker, I can help you determine which one is correct based on these principles of refraction.
