Answer:
d y / x = m λ
Explanation:
When the laser beam, which is a coherent light, hits the slits, part of each beam passes through each slit.
When this is observed on a screen that is quite far from the slits, a series of intense linear separated by dark areas. The explanation for this distribution of the light pattern is that when adding the rays that come out of the slits they travel different distances, which introduces a difference in optical path and if this difference is an integer multiple of the wavelength, a bright line
d sin θ = m λ
Where d is the distance between the slits (0.1 mm)
Also, since the angle of the measurements is small, we can approximate the tangent
tan θ = y / x = sin θ /sin θ
sint θ = y / x
Substituting into the equation
d y / x = m λ
This expression gives the location of the bright lines on the screen
Answer:
1.30 m
Explanation:
The pressure (P) exerted by a column of a liquid can be calculated with the following expression:
where,
ρ is the density of the liquid
g is the gravity
h is the height of the column
If both liquids exert the same pressure:
Answer:
He could have many different hypothesis, but here is one.
Explanation:
If rubber bands are wider, then the rubber bands will stretch further, because the wider a rubber band is the stronger it is.
Answer:
imma need a few answer choices so i can do my research
Explanation:
Please any thank you
Answer:
Sound travels faster in liquids than in gases because molecules are packed more closely together. This means that when the water molecules begin to vibrate, they quickly begin to collide with each other forming a rapidly moving compression wave. Sound travels over four times faster than in air
