The correct Answer is:
To solve the problem of which colored letter appears to be raised more when a plane glass is placed over them, we will follow these steps: ### Step 1: Understand the Concept of Refraction When light passes from one medium to another (in this case, from air to glass), it bends due to a change in speed. This bending of light is known as refraction. The amount of bending depends on the wavelength of the light. ### Step 2: Identify the Relationship Between Deviation and Wavelength The deviation of light when passing through a medium is inversely proportional to its wavelength (λ). This means that shorter wavelengths (like violet) will deviate more than longer wavelengths (like red). ### Step 3: List the Colors and Their Wavelengths The colors of light, in order of decreasing wavelength, are: - Red (longest wavelength) - Yellow - Green - Blue - Indigo - Violet (shortest wavelength) ### Step 4: Determine Which Color Will Appear Raised Since the deviation is greater for shorter wavelengths, the color that will appear to be raised more is the one with the shortest wavelength. Among the colors given (Violet, Green, Yellow, Red), violet has the shortest wavelength. ### Step 5: Conclusion Thus, the letter that appears to be raised more when viewed through the glass is **Violet**. ### Final Answer The letter which appears to be raised more is **Violet**. ---
