How do waves interact with matter ?

Chemistry
1 answer:
velikii [3]2 years ago
6 0
Waves interact with matter in several ways. The interactions occur when waves pass from one medium to another. Besides bouncing back like an echo, waves may bend or spread out when they strike a new medium. These three ways that waves may interact with matter are called reflection, refraction, and diffraction.

A student writes the following explanation of how certain molecules are formed.A process is used to chemically link smaller unit
tensa zangetsu [6.8K]

Answer:

polymerization

Explanation:

Student is explaining the process of formation of a polymer and the process is called polymerization.

Polymer is made up of joining repeating units. The repeating units are called monomers.  

Properties of the polymer is determined by the structure of monomer molecule.

For example, consider a well-known polymer Teflon.is made by the polymerization of tetrafluoroethane.  

Thus, the student is explaining polymerization.

Can swords shatter from cold temperatures
sp2606 [1]
Depends on how the sword is made, what materials are used and temperature used but yes they can shatter.

When molecules cool down they stop vibrating and moving as much and so they "shrink" and the metal of the sword becomes brittle. sometimes they shrink at different phases which cause tension in the sword if this tension is strong enough it can cause the metallic bonds to break causing the sword to shatter.

hope that helps

What are the two types of collisions? What is the difference between them? Types: a. Types: b. Compare and contrast the two type
mr_godi [17]

Answer:

The two types of collisions are :

Type a)

<u>Elastic collision</u>

Type b)

<u>Inelastic collision</u>

Explanation:

Collision : It is the event when two bodies collide with each other for small period of time.

During collision , the bodies exert force to each other.

Example :

When boxer hits with punches .

When bat hits the ball in cricket match.

So, collision is short duration interaction of two objects. When the objects collides , there is  change in their velocity.

All collision follow law of conservation of momentum . Their type is decided by , whether they follow conservation of energy also.

<u>Compare and contrast the two types</u>

a) Elastic collision : Those collision in which no loss or gain of kinetic energy will occur. They follow conservation of kinetic energy. Example : ideal gaseous molecule

b) Inelastic collision : Those collision in which Change in kinetic energy will occur. They do not follow conservation of kinetic energy.Almost all conservation are inelastic.

Here Kinetic energy get converted into other form of energy.
