Question

An incident wave is travelling along a string smoothly joined by two different materials of linear density α and β. If impedances are different in two different section, then prove that, the reflection coefficient at the junction of the two material is​

Answer 1

Answer:

Chlorophyll is any of several related green pigments found in the mesosomes of cyanobacteria and in the chloroplasts of algae and plants. Its name is derived from the Greek words χλωρός, khloros and φύλλον, phyllon. Chlorophyll is essential in photosynthesis, allowing plants to absorb energy from light.

Answer 2

• Any of several closely related green pigments called chlorophyll can be found in the chloroplasts of algae and plants as well as in the mesosomes of cyanobacteria.
• Its name is a combination of the Greek words khloros and phyllon.

• In order for plants to receive energy from light during photosynthesis, chlorophyll is crucial.

When a wave traveling along a string goes from a heavy string to a light string Its?

• At the interface part of the wave is transmitted and part is reflected.
• the interface acts like a fixed end, so the reflected wave is inverted.
• For a wave traveling along a heavy string tied to a light string the reflected part of the wave is not inverted when the wave reflects.

What is the relation between tension in the string and the velocity of the wave on that string?

• The wave speed is proportional to the square root of the tension, so the speed is doubled.
• Guitars have strings of different linear mass density.

What effect does increasing the tension have on the velocity of waves on the string?

• Increasing the tension on a string increases the speed of a wave, which increases the frequency (for a given length).

What does the speed of a wave along a string depend on?

• The speed of a wave on a string depends on the linear density of the string and the tension in the string.
• The linear density is mass per unit length of the string.
• In general, the speed of a wave depends on the square root of the ratio of the elastic property to the inertial property of the medium.
