Question

p8.6 formative 2
the image shows the behavior of three light rays (1, 2, and 3) as they encounter a surface.
which option correctly identifies the behaviors of the light rays?
light ray 1 is absorbed, light ray 2 is refracted, and light ray 3 is reflected.
light ray 1 is absorbed, light ray 2 is reflected, and light ray 3 is refracted.
light ray 1 is refracted, light ray 2 is reflected, and light ray 3 is refracted.
light ray 1 is reflected, light ray 2 is absorbed, and light ray 3 is refracted.

Explanation:

• Absorption: When a light ray is absorbed, it does not pass through or bounce off the surface. Light ray 1 does not emerge on the other side or bounce back, so it is absorbed.
• Refraction: Refraction is the bending of light as it passes from one medium to another. Light ray 2 bends as it enters the new medium (the gray block), so it is refracted.
• Reflection: Reflection is when light bounces off a surface. Light ray 3 bounces back from the surface, so it is reflected.

Answer:

Light ray 1 is absorbed, light ray 2 is refracted, and light ray 3 is reflected.
