No, the density of diamond and graphite would not be the same
Explanation:
What is density?
Density is the amount of substance per unit volume. It is simply mass divided by volume.
Density is greatly influenced by the way substances are packed.
Substances that are well packed will have lower volume for the same amount of matter than another that is poorly packed.
- The carbon atoms in graphite are poorly packed. They are arranged layers upon layers.
- Diamond carbon atoms have a cross-linked networked pattern. They are well packed.
- For the same mass of matter, graphite will take up more space than diamond.
Since:
Density =
The one that has a lesser volume will have a higher density.
Therefore diamond will have a higher density.

Answer:
Width of the slit will be equal to 1.47 mm
Explanation:
We have given wavelength of the light
Distance D = 8 m
Distance between first minimum dark fringe and the central maximum is 2 mm
So
We have to find the width of the slit
For the first order wavelength is equal to , here a width of slit
So
So width of the slit will be equal to 1.47 mm
