Constructive interference occurs when two waves overlap and the resulting wave has a larger amplitude. Hence, option (2) is correct.
What is interference?
The phenomenon in which there is an overlapping between the two waves propagating in a medium is known as interference. The interference is classified into two categories namely,
- Constructive interference
- Destructive interference
Constructive interference -
It occurs when there is a superposition of the two waves such that the resulting wave has a large amplitude.
Destructive interference -
It occurs when there is a superposition of the two waves such that the resulting wave has a lower amplitude.
Thus, we can conclude that constructive interference occurs when two waves overlap and the resulting wave has a larger amplitude. Hence, option (2) is correct.

<h3>Hey Mate Here Is Your Answer</h3>
The branch of physics that defines motion with respect to space and time, ignoring the cause of that motion, is known as kinematics. Kinematic equations are a set of equations that can derive an unknown aspect of the motion of a body if the other aspects are provided.
<h3>Hope This Helps You</h3>
The acceleration a free falling body experiences due to gravity will always remain the same. It will always be -9.8 m/s^2.
Thus, the downward velocity of the body will always be increasing (or decreasing, however you want to think about it) because gravity is acting upon it.
The distance the body has fallen will increase faster and faster over time because its velocity is increasing.
Since this is a right-angled triangle,
Use tan 30 to find BC
Use tan 75 to find AC
Then subtract both answers to find AB
Explanation:
Every valid chemical equation must be balanced i.e the same number of atoms must be present on both sides of the equation.
The law of conservation of mass states that "matter cannot be created nor destroyed in a chemical reaction but are transformed from one form to another".
- A chemical equation contains reactants on the left hand side.
- On the right hand side, the products are formed.
- For the reaction to be valid, there must be equal numbers of atoms of any specie on both sides of the equation.
- This way the law of conservation of mass holds true.
