Answer:

ig might increase a lot

Explanation:

so yeahhhh

Answer 2

Answer:

The Correct Answer would be (1) only (A) is true / (A) మాత్రమే నిజం. In VIBGYOR, the wavelength increase from Violet color to Red color.

Explanation:

• In VIBGYOR, the Red light has the maximum wavelength and the Violet light has the minimum one. This happens because red light is least deviable from it's path. It, most of the time, remains undeviated in atmosphere. This is the same reason why the traffic lights use Red Lights as the sign for stop as because it is lest deviable, it is visible from a very far point. As wavelength ∝  $\frac{1}{deviation}$ ,the wavelength increases from violet to red.
• The Refractive Index, on other hand, is directly proportional to deviation. As deviation decreases from violet to red, therefore, refractive index also decreases, making the given statement incorrect.
