Answer:
None of the wavelength is in the visible range
Explanation:
Constructive interference of the reflected waves for different wavelengths can be estimated using:
λ = 2nd/m
where m is 1,2,3, ...
Therefore:
m=1, λ = 750 nm
m=2, λ = 750/2 = 375 nm
The limits of eye's sensitivity is between 430 nm and 690 nm. Beyond this range, the eye's sensitivity drops to approximately 1% of its maximum value.
Iron & Nickel. There are also small doses of other unimportant garbage.
C is your answer. (Iron & Nickel)
Answer:
The dimensions of Young's Modulus, as well as material stress, are the same as pressure because stress is like pressure in a solid, except with some key differences that warrant the use of different terminology.
Mass and weight are different. Mass is the measurement of how much matter an object has, while weight deals with the pull of gravity. For example, an astronaut floating in space is weightless, due to the limited influence of gravity. But he will still have mass, that is because mass and weight are different :)
