The spring is neither stretched nor compressed. an object having a mass m is attached to the free end of the spring. consider an action
Answer:
Explanation:
This is case of interference in thin films
for constructive interference in thin film the condition is
2μ t = (2n+1)λ/2 ; μ is refractive index of oil , t is thickness of oil , λ is wave length of light .
2 x 1.28 x t = λ/2 , if n = 0
2 x 1.28 x t = 605 /2
t = 118.16 nm .
the minimum non-zero thickness of the oil film required = 118.16 nm.
False.
As temperature increases the more the electrons begin to vibrate more, as it decreases they vibrate less.
Number 5 is A
number 6 is D
