Reflection and Refraction MCQ:
Reflection and refraction are important concepts in the study of light and its behavior. Here are some multiple-choice questions to test your understanding of these concepts:

1. Which of the following best describes reflection?
A. Light passing through a medium without changing direction
B. Light bending as it passes from one medium to another
C. Light bouncing off a surface
D. Light slowing down as it moves through a medium
Answer: C. Light bouncing off a surface

2. When light travels from a less dense medium to a more dense medium, it undergoes:
A. Reflection
B. Refraction
C. Absorption
D. Transmission
Answer: B. Refraction

3. The law of reflection states that:
A. The angle of reflection is equal to the angle of incidence
B. The angle of reflection is greater than the angle of incidence
C. The angle of reflection is less than the angle of incidence
D. The angle of reflection is perpendicular to the angle of incidence
Answer: A. The angle of reflection is equal to the angle of incidence

4. Which of the following phenomena is caused by refraction of light?
A. Rainbows
B. Shadows
C. Mirages
D. Polarization
Answer: C. Mirages
Reflection occurs when light bounces off a surface, following the law of reflection which states that the angle of reflection is equal to the angle of incidence. Refraction, on the other hand, occurs when light bends as it passes from one medium to another with different optical densities. This bending of light can lead to phenomena like mirages. Understanding these concepts is crucial in various fields such as optics, photography, and even in everyday experiences like seeing rainbows or shadows.
