The answer is A because it is an example of red shift which if basically the Doppler effect , but for light. The wavelength gets longer because it has visible light has shifted into the red end of the spectrum, showing that it has a shorter frequency with a longer wavelength; meaning it is moving away from us
Answer:Combustion
Explanation:The chemical reaction is called combustion and requires oxygen. Combustion changes the potential chemical energy into kinetic energy in form of heat.
As you crank the variable resistor to higher resistance, the total current in the loop decreases. The power dissipated by the light bulb ... the heat and brightness it produces ... depend directly on the current through it, so they decrease too. Your circuit is a perfect incandescent light dimmer circuit.
Answer:
0.00000011 m
Explanation:
n = 0 for minimum thickness
t = Thickness
= Refractive index of the film = 1.25
= Wavelength = 
We have the formula
The minimum thickness of the film is 0.00000011 m
