The visible spectrum:
The visible spectrum refers to the range of electromagnetic radiation that is visible to the human eye. It consists of various colors that we can perceive, ranging from red to violet.

The lower end of the visible spectrum:
At the lower end of the visible spectrum, we find the color violet. Violet light has the shortest wavelength and highest frequency among the visible colors. It can be seen at the end of a rainbow or when sunlight passes through a prism, causing the colors to separate.

The upper end of the visible spectrum:
At the upper end of the visible spectrum, we find the color red. Red light has the longest wavelength and lowest frequency among the visible colors. It can also be seen in a rainbow, appearing at the opposite end of violet.

The correct answer:
The correct answer to the question is option 'A', which states that violet is at the lower end and red is at the upper end of the visible spectrum. This is because violet light has a shorter wavelength and higher frequency compared to red light.

Violet light has higher refractive index than the red light.
Thus, the focal length for red light is greater. 
This means that the red light has lower tendency to get refracted than the violet light.
