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.

Answer:
Look below.
Explanation:
All the symptoms provided points to the common problem of dehydration. Especially a physically active person because they are constantly sweating which leads to the loss of bodily fluids and dehydration.
The charge would be in equilibrium so there would be no charge in the body of the conductor.
Answer:
(b) there cannot be any charge in the body of the conductor
Answer:
Less gravity and Vacuum
Explanation:
As per the laws of gravity, acceleration due to gravity is independent of mass of an object. That means if you drop two objects of different mass form same height with zero initial speed, they will reach the ground at the same time.
Galileo had given this theory and proved it. But when you take one object as feather the presence of air makes it float and the law seems to fail. The law is correct but the only reason it fails is because the feather starts floating in the air.
To prove this we need a vacuum chamber with a great height to witness the free fall condition. Creating such a chamber on Earth is very difficult. David Scott had these advantages on the Moon. As Moon doesn't have any atmosphere so he got a natural vacuum environment.
Also, as the acceleration due to gravity on Moon is of that on the Earth, it will take less time to touch the surface and one can easily observe the free fall without any aid of high speed camera.
