How are the interference patterns for light through a double slit and light through a single slit similar yet different

Physics
1 answer:
xxMikexx [17]2 years ago
3 0

Answer: In double slit case, you need to understand superposition on waves emerging from dirrerent slit.

Explanation: When passing a single slit, wave spread in all directions.

In double slit waves with equal wavelength travel different path and distance  

trey travel is different . Waves meet each other in different positions in different phases. If phase are same, waves have contructive interference, crests of waves meet in same point. Amplitudes of waves are added together. If waves are in opposite phases, sum of amplitudes

ame subtacted and this is destructive interference. Sum of amplitudes are zero.

1. Which one of the following physical quantities is formed after dividing<br>mass by volume?​
aivan3 [116]

Answer:

xxxxx

Explanation:

Density is the mass of an object divided by its volume. Density often has units of grams per cubic centimeter (g/cm3). Remember, grams is a mass and cubic centimeters is a Volume (the same volume as 1 milliliter).

Plz help me!!!! A spring is connected to a wall as shown below. A mass on a horizontal surface is connected to the springs and p
kirill [66]

Answer:

320 N/m

Explanation:

F = k·Δx

where

F is the restoring force of the spring

k is the proportionality constant called the ‘spring constant’

Δx is the change in the spring’s position due to the deformation.

You need the k so

25 cm= 0.25m

k=F/∆x = 80/0.25 = 320 N/m

Why are marble and granite used so often as a building materials?
Katyanochek1 [597]

Answer:

Granite is an excellent building material that provides some outstanding interior design opportunities whilst being incredibly sturdy and reliable. It has become one of the most popular building materials in modern construction, from kitchen surfaces through to paving slabs.You Can Expect Durability and Longevity. Firstly, marble is so popular around the world because of its durability in a wide variety of weather conditions. Structures that are over hundreds of years old made from marble are still standing to this day, and look as pristine as they day they were crafted.

Determine W (or fuel energy) required to launch a satellite of mass m at rest from a launching pad placed at the surface earth,
jeka57 [31]

Answer:

5. 9GmM/(10R)

Explanation:

m is the mass of the satellite

M is the mass of the earth

W is the energy required to launch the satellite

Energy at earth surface = Potential energy (PE) + W

W = Energy at earth surface - Potential energy (PE)

But PE = -\frac{GMm}{R}

Therefore: W = Energy at earth surface - \frac{GMm}{R}

Energy at earth surface (E) at an altitude of 5R = -\frac{GMm}{5r} +\frac{1}{2}mV^2

But V=\sqrt{\frac{GM}{5R} }

Therefore: E=-\frac{GMm}{5R}+\frac{1}{2}m(\sqrt{\frac{GM}{5R} } )^2=  -\frac{GMm}{5R}+\frac{GMm}{10R}  = -\frac{GMm}{10R}

W = E - PE

W=-\frac{GMm}{10R}-(-\frac{GMm}{R})=-\frac{GMm}{10R}+\frac{GMm}{R}=\frac{9GMm}{10R} \\W=\frac{9GMm}{10R}
