Explanation:
When the incident light is yellow the width of the central band greater. Single-wavelength light sources are known as monochromatic lights, where mono stands for one and chroma for color. Monochromatic lights are defined as visible light that falls inside a specific range of wavelengths. It has a wavelength that falls within a constrained wavelength range.
A laser beam is the ideal illustration of monochromatic light. A monochromatic light beam produced by a single atomic transition with a particular single wavelength is what makes up a laser. A color scheme that consists solely of different shades of one color is referred to as monochromatic.

The tilt of the earth on its axis causes the seasons.
Answer:
b) Demultiplexer.
Explanation:
The multiplexed signal occupies the total bandwidth of the communications channel, while that the constituent component signals, occupy only a small part of the bandwidth.
Prior to be demodulated, they must be separated each other, which is done (in a FDM multiplexing scheme) using a series of band-pass filters.
Examples of physical properties include: color, shape, size, density, melting point, and boiling point.
