Answer:
2.00m
Explanation:
All we need to do to find the wavelength of the first intereference maximum is subtract both values we are given.
8.00 - 6.00 = 2.00m
Best of Luck!
Answer:
F. Either B or C
Explanation:
The beat frequency is the difference of two frequencies of two waves.
Here, one wave has frequency 610 Hz and the beat frequency is 3 beats per second.
It is not mentioned which has a higher frequency. So, there are two possiblities.
or
Hence, the frequency of the other wave is 613 or 607.
Regular reflection is a reflection such that the the angle of reflection of the light is equal to the angle of incidence and it is on the opposite of the normal to the point of incidence. In a regular reflection the incident ray, the reflected ray and the normal to the reflection all lie in the same plane. Regular reflection happens if the reflection surface is very smooth.
You’re right, bc I’m the question it says the pulley is at equilibrium
