Answer:
The intensity of light be maximum is for angles 23.3° and 52.3°.
Explanation:
Given that,
Wave length = 632.8 nm
Distance = 1.60 μm
We need to calculate the intensity of light be maximum
Using Bragg's law
We need to calculate the angle for different value of n
Using Bragg's law
For n₁,
Put the value into the formula
For n₂,
Hence, The intensity of light be maximum is for angles 23.3° and 52.3°.
Answer:
im pretty sure it should be 50.0
Answer:
4) Isaac Newton was the first scientist to propose the idea that gravity increases distance between objects decrease
Explanation:
1 - Kepler may have inspired most of Newton's propositions, but there is no record of collaborating on the theory of universal gravitation.
2 - The universal gravitation theory resemble the works of other great scientists, but Newton was indeed the first to propose this idea of gravitation
3 - On the contrary, these scientists have shared concepts, with differences in accuracy that supersede each other to be accepted by the community (i.e: Einstein being at the forefront despite sharing some ideas with Newton)
