Do waves actually move up and down?
Do waves actually move up and down? We notice that while it moves up and down it does not move in the direction of the wave’s propagation. A wave can be transverse or longitudinal depending on the direction of its oscillation. While mechanical waves can be both transverse and longitudinal, all electromagnetic waves are transverse. […]
Why is maximum wavelength important?
Why is maximum wavelength important? Another reason for using the wavelength with maximum absorbance is that is decreases interference from the equipment. On the other hand, at wavelength B there is better absorbtion, so a change in concentration will give a much more significant change in absorption. What is the basic principle of UV Visible […]

What happens when iron is mixed with Sulphur?
What happens when iron is mixed with Sulphur? When iron filings and sulphur powder are mixed and heated they undergo a chemical reaction and form ferrous sulphide (FeS). It is a new substance which has properties entirely different from Fe and S. Therefore, heating of a mixture of iron and sulphur powder is a chemical […]
