I am 95% sure the answer is Newton hope this helps (sorry if I’m wrong I’m a little sleep deprived)
Answer:
When a light wave goes through a slit, it is diffracted, which means the slit opening acts as a new source of waves. How much a light wave diffracts<em> (how much it fans out)</em> depends on the wavelength of the incident light. The wavelength must be larger than the width of the slit for the maximum diffraction. Thus, for a given slit, red light, because it has a longer wavelength, diffracts more than the blue light.
The corresponding relation for diffraction is
,
where is the wavelength of light, is the slit width, and is the diffraction angle.
From this relation we clearly see that the diffraction angle is directly proportional to the wavelength of light—longer the wavelength larger the diffraction angle.
Answer:
32°
Explanation:
From the diagrammatic representation of the question,
Point A is the pilot point of view from the airplane
Point C is the foot of the first tree
Point D is the foot of the second tree
Line AB is the height of the airplane from the ground level.
Line CD is the distance between the two trees
Considering ΔABC,
tan 33°
BC = 5000 / tan 33°
BC = 7,699.41 feet
BD = BC + CD
BD = 7,699.41 + 300
BD = 7,999.41 feet
Considering ΔABD,
tan θ
tan θ
tan θ = 0.6250
θ = tan⁻¹ 0.6250
θ = 32°
Answer:
unknown wavelength is 540 nm
Explanation:
given data
wavelengths = 600 nm
10th bright fringe overlap = 9th bright fringe of 600 nm
to find out
unknown wavelength
solution
we get here first nth bright fringe from the central maximum at distance y
y = n × ...............1
and we have given 10th bright fringe overlap = 9th bright fringe of 600 nm
so here
10 × = 9 × 600 ×
solve it we get
= 9 ×
= 540 nm
so unknown wavelength is 540 nm
