it will produce rainbow of colours...
I think the farthest color next to white is red
A red slit.
yes
Diffraction
if the width of one slit is increased relative to the other the slit separation must decrease and since slit sep is inversely proportional to fringeseparationthe fringes become closer together.
There will be no interference because intensity of light reflected from mirror will be so great that it won't be visible and we will get uniform illumination.
The purpose of the slit in the spectroscope is to regulate the amount of light that comes in. Without the slit, light would come from various angles.

Any small slit will scatter light. Especially blue light.
The purpose of a slit is to cause diffraction of the light. This means the light spreads out in all directions, as opposed to entering a large hole where the light would pass straight through in its original direction.
In quantitative analyses, we use wider slit width to let the slit more brightness, to improve the sensitive of detection. In qualitative analysis, we use narrow slit to get higher resolution, avoid other light influence and to detect the specific light wavelength.
Two narrow slits with gap 0.03 mm and got separated by 3 mm will be illuminated by a monochromatic light which comes out of single slit. These two slits are named as Young's double slits. The waves coming out of these two will be in coherence.

The slit lamp is a microscope with a light source that can be adjusted. This magnifies the external and some internal structures of the eyes. The lid and lid margin, cornea, iris, pupil, conjunctiva, sclera, and lens are examined. The slit.
