Constructive interference happens when this condition is satisfied:
This means that the difference in the distance traveled by the waves, from the slit to the screen, is equal to the whole multiple of the wavelength.
If we say that the distance between two interference fringes is much smaller than the distance from the slit to the screen, we can use the following approximation:
Finally for the bright spots we have:
The spacing between bright spots is:
Answer:
3400 m
Explanation:
Both lightning and thunder happen at the same time but one is faster than the other. The distance traveled by a sound can be calculated from its speed such that;
speed = distance/time, hence, distance = speed x time.
<em>For a thunder with 340 m/s speed and 10 seconds away from lightning, the distance between the thunder and the lightning can be calculated as</em>;
distance = 340 m/s x 10 s = 3400 m
Distance is the physical length travelled. While the displacement is the shorter distance between any two given points.
<h3>What is distance?</h3>
Distance is a numerical representation of the distance between two objects or locations.
Distance can refer to a physical length or an estimate based on other factors in physics or common use. |AB| is a symbol for the distance between two points A and B.
Displacement is defined as the shortest distance between the two points.
Sam determines the distance by doing the calculation as;
distance = speed × time
Hence, the Sam determines the distance and displacement by the respective formulas.

Answer:
the statement that best compares potential and kinetic energy would be only kinetic energy increases when velocity of an object increases
Explanation:
A fiber-optic cable is made up of incredibly thin strands of glass or plastic known as optical fibers; one cable can have as few as two strands or as many as several hundred. Light travels down a fiber-optic cable by bouncing repeatedly off the walls. If<span> light hits glass at a really shallow angle (less than 42 degrees), it reflects back in again—as though the glass were really a </span>mirror<span>. This phenomenon is called </span>total internal reflection<span>. It's one of the things that keeps light inside the pipe.</span>
