Diffraction and interference

What is resonance and how does it happen?

If that frequency happens to match the resonant frequency of the object it's hitting, then you'll get what's called resonance. Resonance occurs when the amplitude of an object's oscillations are increased by the matching vibrations of another object.

What is a node? What is a antinode?

These are the points that undergo the maximum displacement during each vibrational cycle of the standing wave. In a sense, these points are the opposite of nodes, and so they are called antinodes. A standing wave pattern always consists of an alternating pattern of nodes and antinodes.

How does diffraction affect the perceived detail?

To perceive greater detail a dolphin emits sounds of higher frequency. ?

How is a beat formed?

When two sound waves of different frequency approach your ear, the alternating constructive and destructive interference causes the sound to be alternatively soft and loud

What is Young's Experiment? What was its main conclusion?

Young's interference experiment, also called Young's double-slit interferometer, was the original version of the modern double-slit experiment, In 1801, a scientist called Thomas Young developed the double slit experiment which conclusively proved whether light was a particle or wave.

standing wave

a pattern of vibration that simulates a wave that is standing still

What is diffraction? What types of waves get diffracted?

breaking white light into various components and by bending each color component of white light at a different angle, light waves are diffracted

What affect the amount of diffraction and in what way?

measured by the wave and the wavelength and are measured at different angles.

What is interference? When does it occur? What are the two possible types of interference?

the action of interfering or the process of being interfered with. Destructive interference occurs when waves come together in such a way that they completely cancel each other out. Wave interference is the phenomenon that occurs when two waves meet while traveling along the same medium. Destructive interference is a type of interference that occurs at any location along the medium where the two interfering waves have a displacement in the opposite direction.

What is a natural frequency?

the frequency at which a system oscillates when disturbed
