Question

Given below are two statements:
Statement 1: Image formation needs regular reflection and/or refraction.
Statement 2: The variety in colour of objects we see around us is due to the constituent colours of the light incident on them.
In the light of the above statements, choose the most appropriate answer from the options given below :

• A. Statement I is correct but statement II is incorrect
• B. Statement I is incorrect but Statement II is correct
• C. Both Statement I and Statement II are correct
• D. Both Statement I and Statement II are incorrect

Answer 1

The Correct Option is C

Let's analyze both statements given in the question and determine their correctness based on fundamental physics concepts:

1. Statement 1: Image formation needs regular reflection and/or refraction.
   • Regular reflection refers to the reflection of light from a smooth surface where it follows the laws of reflection (angle of incidence equals angle of reflection). This process is crucial for forming clear images, as seen in mirrors.
   • Refraction occurs when light passes from one medium to another, leading to a change in its speed and direction. Lenses use refraction to focus light and form images, such as in cameras and eyeglasses.
   • Thus, both regular reflection and refraction are fundamental processes for image formation in optical systems. Therefore, Statement 1 is correct.
2. Statement 2: The variety in the color of objects we see around us is due to the constituent colors of the light incident on them.
   • Objects appear colored because they reflect certain wavelengths of light while absorbing others. The color we perceive depends on the wavelengths that are reflected.
   • For example, a red apple appears red because it reflects red wavelengths from the incident white light, which contains all visible colors.
   • Hence, the statement accurately describes how we perceive the variety of colors, making Statement 2 correct as well.

Conclusively, as per the physics principles concerning reflection, refraction, and color perception, both statements are correct. Therefore, the correct answer is: Both Statement I and Statement II are correct.
