Explanation:</h3>
Concept being tested: Waves and types of waves
To answer the question we need to define both electromagnetic waves and mechanical waves.
- Waves can be classified as either electromagnetic waves and mechanical waves based on whether they require a material medium for transmission or not.
- Electromagnetic waves do not require a material medium for transmission and can travel through a vacuum.
- Mechanical waves, on the other hand, are waves that require a material medium for transmission.
What are examples of electromagnetic waves and mechanical waves?
- Examples of electromagnetic waves include gamma rays, radio waves, visible light, etc.
- Examples of mechanical waves include sound waves and water waves.
Therefore, the answer to our question is;
- Electromagnetic waves are not mechanical waves, which means they can travel in a vacuum.
Answer:
I do agree with the student. Because imagene you have a tissue and a stick. And you throw them at the same speed , the stick will go farther because it' s heavier but the tissue would just blow around and not go forward because it is not heavy enought.
Explanation:
Hope this is correct have a terrific day.
Answer:
At focus
Explanation:
A concave mirror is converging in nature. In a mirror, concave in nature, the rays which are parallel to the principal axis are supposed to be coming from very large distances or we assume the source to be placed at infinity for such rays which are parallel to the principal axis.
These rays, parallel to the principal axis, coming from infinity, converges at the focus of the mirror concave in nature after reflecting from the concave mirror
1. Communication
In early ages people were using letters to communicate between them. Now days instantly we can call one person from anywhere, these are based on optical fiber communication and it is an application of physics.
2. Transportation
We can travel from place to anther place by aeroplane , these technologies are introduced after advancement in physics.
3. Construction
Earlier people used to stay in small houses, now days apartments with many number of storeys are built by considering all the forces coming on the structure.
4. Medical Department
The invention of many equipment increased the health of humans.
5. Weather forecasting
The prediction of weather considering all the available factors, prediction of natural disasters all are application of physics.
