Question

which scenario below represents that refraction of light?○ incident light rays hit a smooth, flat surface and bounce off at the exact same angle they arrived.○ a light ray travels from air into a glass block. as it enters the glass, the ray bends and travels at a new angle, then bends again as it exits.○ parallel light rays hit a rough, uneven surface. the rays bounce off in many different, scattered directions.○ white light hits a solid black surfacce. no light rays bounce off or pass through; the arrows simply end at the surface.std: 8.ess2.3type: multiple choicequestionquestion #12title: 8.ps4.2std: 8.ps4.2type: multiple choicequestionquestion #13title: 8.ess2.4std: 8.ess2.4type: multiple choicequestionquestion #14title: 8.ess3.1std: 8.ess3.1type: multiple choicequestionquestion #15title: 8.ess2.2std: 8.ess2.2type: multiple choicequestionquestion #16title: 8.ess2.2std: 8.ess2.2type: choice matrixquestionquestion #17title: 8.ps2.1std: 8.ps2.1type: multiple choicequestionquestion #18title: 8.ess2.4std: 8.ess2.4type: multiple choicequestion

Explanation:

Refraction is the bending of light as it passes from one transparent medium to another with a different optical density.

• The first option describes specular reflection (smooth surface reflection).
• The second option describes light bending when moving between air and glass, which is refraction.
• The third option describes diffuse reflection (rough surface scattering).
• The fourth option describes absorption of light.

Answer:

A light ray travels from air into a glass block. As it enters the glass, the ray bends and travels at a new angle, then bends again as it exits.
