Fourth Harmonic-Standing Waves on a String
There are a variety of patterns that could be generates through vibrations inside a string, slinky, or rope. Every pattern corresponds to vibrations that occur at a particular frequency and is called as a harmonic. The lowest possible frequency at that a string could vibrate to form a standing wave pattern is called as the fundamental frequency or the first harmonic.
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?

a pendulum is timed ,first for 20 swings and then for 50 swings ; time for 20 swings = 17.4 sec and time for 50 sec = 43.2. calculate the average time per swing/
Concept of wave front The basis of Huygens wave theory of light is his principle concerning construction of wave front. When a disturbance from a light source travels i
It is the property of a material by virtue of which it allows itself to be magnetized. Permeability varies from material to material depending upon the saturation and temperature.
