Explanation: Nondestructive testing or Evaluation is a term used in the field of science and technology to describe the evaluations, analysis or testing carried out on components of materials without destroying any part or components of the test materials. It is very useful in scientific research or industrial engineering environments. When any disruption of physical structure or configuration of a component will lead to discontinuing of the test, and it may not affect the usefulness of the affected parts.
Answer:
1.5 x 10¹⁴
Explanation:
For the nucleus :
= radius of proton = 1.0 x 10⁻¹⁵ m
= mass of proton = 1.67 x 10⁻²⁷ kg
density of nucleus is given as
= 3.98 x 10¹⁷
For the atom :
= radius of atom = radius of proton + radius of orbit = (1.0 x 10⁻¹⁵ + 5.3 x 10⁻¹¹) m
= mass of atom = mass of proton + mass of electron = 1.67 x 10⁻²⁷ + 9.31 x 10⁻³¹ kg
density of atom is given as
= 2680.5
Ratio is given as
= 1.5 x 10¹⁴
Answer:
At some point on say, the receiving screen, light emanating from the left side of the slit will be out of phase (a difference of 1/2 wavelengths) from light coming from the center of the slit.
Thus for every point that is left of the center of the slit, there will be a point on the right side of the slit that is out of phase,
There will be no light on the screen at that particular point and thus there will be a dark fringe there.
That is the basic explanation for the appearance of dark and bright fringes on the receiving screen.

Hi Linda,
How's it going?
Sorry I haven't been in touch for such a long time but I've had exams so I've been studying every free minute. Anyway, I'd love to hear all your news and I'm hoping we can get together soon to catch up. We just moved to a bigger flat so maybe you can come and visit one weekend?
How's the new job?
Looking forward to hearing from you!
Helga
