Answer:
answer should be 10 because the line goes from (0,0) then to (1,10) and so on
Main answer: 7.68
Supporting answer: Diffraction
Diffraction of light is the phenomenon where the bending of light happens around corners such that it spreads out and illuminates areas where the formation of shadow is expected.
The diffraction of light is divided into two types:
- Fresnel diffraction: Here the division of light is from a point source and incident and diffracted wavelengths are spherical
- Fraunhoffer diffraction: Here the division of light is from a point source or multiple source and incident and diffracted wavelengths are parallel.
Here diffraction grating, is defined as an optical element that divides the light into various wavelengths.
The formula for diffraction is: dsinФ=nλ
where, d is the distance between the slits, Ф is the diffracting angle, n is the order number and λ is the wavelength.
Given, grating is 2090 grooves per centimeter for n=1,
d=n/λ
Then,
Therefore,
dsinФ=nλ
sinФ=nλ/d
Ф=
Therefore, the red light appears at an angle of 7.68

Hello! Your answer would be D. Interference
This is because interference causes vibration!!!
his displacements are given as
East
North
now we can find the direction of displacement by using the concept
magnitude of displacement is given as
<em>so the displacement is 17 km at angle 28.1 degree North of East</em>
