What is antinode ?

What is lanthanide contraction? What are causes of lanthanide contraction

Assertion: An open organ pipe of certain length has the same fundamental frequency as closed organ pipe of half the length. Reason : In case of an open organ organ pipe, at both the ends antinodes are formed while in case of closed organ pipe, at one end antinode and at the other end node is formed.

If a stationary waves is incidnet on a rigid wall, then the distance between wall and first antinode is (its velocity is 36m/s and frequency 72 Hz)

What is an atom and moleule ? What are isotopes?

What is Avagadro number ? What is a mole ?

What is chromatin material? What are its types?

What are pressure node and pressure antinode ?

In a stationary wave, at the antinods there is a change in

In stationary waves, antinodes are the points where there is

Explain formation of stationary wave on astretched string. Show that the distance between node and adjacent antinode is lambda//4 .
