A medium is known as denser if the velocity of ray in that phase is fewer than the speed of the wave in other phase.
In comparison to air velocity of sound is main in water, as water is rarer phase for sound waves w.r.t. air. But it is not right for light (EM-waves). For light rays water is denser medium w.r.t. air.
i need to think of a project to assemble as soon as possible but i need some ideas.. what projects can i present??

What is a neutron? A neutron is a subatomic particle. Neutron is one of the building blocks of the atom. It has a mass of about 1.675 x 10-27 kg. Its spin is + 1/2 and that
An atom of argon(18 protons, 19 neutrons) is ionised by the removal of two orbiting electrons. Q) How many protons and neutrons are there in this ion?
All the traveling waves satisfy a differential equation which is known as the wave equation
Explain Newton Second Law - Linear Motion If objects only followed Newton's first law then everything would be traveling in straight lines at a constant velocity or at rest. B
A circuit contains of a 10 volt battery connected in series with a 4 ohm resistor and a 6 ohm resistor. A person computes the current through the 4 ohm resistor using Ohm's Law by
electric field
Q. How much should be the voltage of an X-ray tube so that the electrons emitted from the cathode may give an X-ray of wavelength 1 A o after striking the target? λmin = 124
