the diagram shows two objects made of the same kind of glass. which statement best compares light passing through the two blocks? light is not separated by wavelength as it exits object x. light moves faster as it moves within object x. light is only refracted once as it passes in and out of object y.

the diagram shows two objects made of the same kind of glass. which statement best compares light passing through the two blocks? light is not separated by wavelength as it exits object x. light moves faster as it moves within object x. light is only refracted once as it passes in and out of object y.

Answer

Explanation:

Step1: Recall refraction concepts

Refraction occurs when light passes from one medium to another. For a rectangular - shaped object like Object Y (a cube), light enters the cube (first refraction) and then exits the cube (second refraction). For a non - rectangular prism like Object X, the path of light and refraction is more complex.

Step2: Analyze each option

  • Option 1: In a non - rectangular prism like Object X, light can be separated by wavelength (dispersion) as it exits, so this is incorrect.
  • Option 2: The speed of light in a given medium depends on the refractive index of the medium. Since both objects are made of the same kind of glass, the speed of light within both objects is the same, so this is incorrect.
  • Option 3: When light passes through a rectangular object like a cube (Object Y), it undergoes refraction once when entering and once when exiting. This is correct as the geometry of the cube causes a simple two - step refraction process.

Answer:

Light is only refracted once as it passes in and out of Object Y.
