Answer: 99.64 nm (≅ 100 nm)
Explanation: In order to explain this problem we have to obtain destructive inteference from two waves that reflect in the film and lens surface so both waves have a λ/2 shift then we have to get a difference path (2L) equal to an odd number of the half wavelegth.
Then we have the following expression:
L=(m+1/2)* λ/(2*n2); where n2 is the refractive index of the coating
for m=0 we have the minimum thickness for the coating
L=λ/(4*n2)=99.64 nm (≅ 100 nm)
Answer:
No
Explanation:
Acceleration = Velocity/Time
An example of where the velocity would be different is:
Acceleration = (automobile 1)
Acceleration = (automobile 2)
As you can see, the velocity for the first automobile is 10 m/s while the second one has a velocity of 25 m/s (with a greater time travelled) and both resulted in the same acceleration of 5 m/s².
I'm pretty sure its D. Both B. and C.
I think the answer is c because the rest are false
