Answer:
a). m/s
b). 1.23 m/s
Explanation:
Given :
Index of refraction for water, = 1.33
Index of refraction of diamond, = 2.42
We know that,
Refractive index of any material is given by,
where c = sped of light in air
v = speed of light in any medium
a). Speed of light in water
m/s
b). Speed of light in diamond
= 1.23 m/s
Explanation :
Barfoed's test : Monosaccharides and reducing disaccharides can be distinguish by this test. The test solution is prepared by dissolving copper (II) acetate in acetic acid.
The equation for the oxidation of glucose by CuO is:
(1)
(2)
Here, CuO act as a catalyst.
In this reaction, first CuO salt get oxidized to form and then get reduced to back (CuO).
Hence, the equations are written above.
Oceanic crust is the relatively thin part of the earths crust which underlies the ocean basins. it is geologically young compared with the continental crust and consists of basaltic rock overlain by sediments
