What is an antinode ?

The equation of a stationary wave is y =0.05 sin 200 pi t cos pi x with all quantities in SI units. What is the maximum speed of a particle at an antinode ?

When longitudinal stationary waves are produced in a medium, then the physical characteristics changes at antinode is / are

The value of amplitude at an antinode , on an undamped one dimensional stationary wave of wavelength 1.2 m, is 5mm. Then the value of amplitude of particle at a distance of 15cm from an antinode is

In a stationary wave that forms as a result of reflection of waves from an obstacle, the ratio of the amplitude at an antinode to the amplitude at node is 6. What percentage of energy is transmitted?

When a string is vibrating in a standing wave pattern , the power transmitted across an antinode , compared to the power transmitted across a node , is

In a stationary wave pattern that forms as a result of reflection pf waves from an obstacle the ratio of the amplitude at an antinode and a node is beta = 1.5. What percentage of the energy passes across the obstacle ?

In a stationary wave that forms as a result of reflection of wave from an obstacle, the ratio of this amplitude at an antinode to the amplitude at anode is n. The friction of energy reflected is
