Question

16.An object is accelerated from rest to some velocity v near the speed of light. If we calculated the energy required using the theory of special relativity, we would obtain result than if we calculated the energy required using classical Newtonian mechanics. O a larger O a smaller the same 17.Consider reflection of light from a thin film of thickness d is the wavelength of the light in the equal to N/4 where film. m1 1a The reflected light from the two surfaces will constructively interfere if O n1

Explanation / Answer

16. a Larger   

17. 2d = lambda/2   

so inteference will be destructive if both reflaction are from denser surface  

so for constructive interference

n1<n3<n2
