It's harder to block sound because sound waves and transverse waves, causing the sound to bounce off objects. This isn't the same with light. Hope that helps.

<span>Distance is the actual path covered and displacement is the shortest distance from the object to the point of origin.
Distance is a total of 10m because you walked 6m initially and then another 4m. 6m + 4m = 10m
Displacement includes the starting point. You walked 6m North. Then you turned around and walked 4m South. Your total displacement is 2m because that is your current distance from the starting point.

If the electron goes a distance d, the amount of work done on it by the magnetic field is zero.
Because magnetic force acts perpendicular to the direction of motion, it has no effect on any moving charge particle. As a result, speed won't change.
<h3>What is Magnetic field?</h3>
- The magnetic influence on moving electric charges, electric currents, and magnetic materials is described by a magnetic field, which is a vector field.
- A force perpendicular to the charge's own velocity and the magnetic field acts on it when the charge is travelling through a magnetic field.
- A compass, a motor, the magnets that hold items in refrigerators, railroad tracks, and modern roller coasters are examples of devices that use magnetic force.
- A magnetic field is created by all moving charges, and any charges that move across its regions are subject to a force.
