Question 336: Ray Optics

Question

Given below are two statements:
Statement I : Image formation needs regular reflection and/or refraction.
Statement II : 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 :

Accepted Answer

The correct answer is
Option C: Both Statement I and Statement II are correct.
Here's why:
Statement I: Image formation needs regular reflection and/or refraction.
This statement is
correct
. Image formation relies on the interaction of light with surfaces. Here's how:
Regular Reflection:
This occurs when parallel rays of light strike a smooth surface and reflect back in a parallel manner. Mirrors are a prime example of regular reflection.  This type of reflection allows for clear, focused images.
Refraction:
This occurs when light passes from one medium to another (like from air to water or air to glass). The change in speed causes the light to bend, resulting in image formation. This is how lenses in cameras, telescopes, and our own eyes work.
Statement II: The variety in colour of objects we see around us is due to the constituent colours of the light incident on them.
This statement is also
correct
.  The colors we perceive are based on the interaction between light and objects:
White Light:
Sunlight or light from a bulb contains all the colors of the rainbow (the visible spectrum).
Selective Absorption:
Objects absorb certain colors of light and reflect others. For instance, a red apple absorbs most colors except red, which it reflects back to our eyes.
Pigments:
Many objects, especially those we paint or dye, contain pigments that absorb specific colors and reflect others.
In summary, both statements are essential to understanding how we see images and perceive colors.
