Explanation:
y1 = 16.2/2 = 8.1 cm
d = 1.22 lambda D/y1
d = 1.22 x 657 x 10^-9 x 23.7/0.081
d = 2.35 x 10^-4 m = 234.52 um

Answer:
Explanation:
Given:
specific heat capacity of quartz,
mass of water,
initial temperature of quartz,
initial temperature of water,
final settled temperature of water after quartz is put into it,
Now by the law of conservation of energy using heat equations:
where:
specific heat of water = ,
is the mass of quartz.
