Answer:
Explanation:
It is given that,
Wavelength in vacuum,
Wavelength in vacuum,
Refractive index for air,
First refractive index,
Second refractive index,
A ray is incident at an angle of incidence of 50 degrees. Let r is the angle of refraction. Firstly calculating the angle of refraction for two values of wavelength from Snell's law as :
For 450 nm,
r = 32.13 degrees
For 650 nm,
r' = 32.65 degrees
Let is the angle of dispersion between the two refracted rays in the oil such that,
So, the angle of dispersion between the two refracted rays in the oil is closest to 0.52 degrees.
If it’s loud enough for your family to hear it, it’s best you turn it down. It could cause permanent damage to your ear drums if it’s loud enough and you could start to lose your hearing. So if your family were to tell you to turn it down, you should probably just turn it down!
Answer:
Work is defined as the process of energy transfer to the motion of an object through the application of force. This is usually represented as the product of force and displacement. The SI unit of work is Joule.
Explanation:
Power is defined as the amount of energy transferred in unit time. The SI unit of power is the watt. One watt is equal to one joule per second. Power is a scalar quantity.
If you think more specifically about energy,such as thermal energy,the amount of that energy a substance has is determined by the movement of the molecules.hope this helps u
