A laboratory experiment produces a double-slit interference pattern on a screen. The point on the screen marked with a white dot

(on a DARK fringe this time) is how much farther from the left slit than from the right slit

Alenkasestr [34]2 years ago
3 0

Explanation:

Diffraction is a characteristic phenomenon for waves, and is based on their variance to find an obstacle or a crack. The diffraction and interference are inseparable phenomena, which are so harder to identify. Since diffraction is a specific type of interference.

if the point are in the order 2, and

the equation is d×senx=mL y at m=2

Lightning flashes one mile (1609 m) away from you. How much time does it take the light to travel that distance?
hichkok12 [17]

Answer:

t=5.36\times 10^{-6}\ s

Explanation:

Given that,

Lightning flashes one mile (1609 m) away from you.

We need to find the time it take the light to travel that distance. Let the time be t. We know that,

speed = distance/time

t=\dfrac{d}{v}\\\\t=\dfrac{1609}{3\cdot10^{8}}\\\\=5.36\times 10^{-6}\ s

So, the required time is 5.36\times 10^{-6}\ s

A frictionless pendulum is made with a bob of mass 19.7 kg. The bob is held at height = 0.934 meter above the bottom of its traj
Alika [10]

Answer:

265 J

Explanation:

Energy=PE+KE=mgh+ 0.5mv^{2} where KE is kinetic energy, PE is potential energy, m is the mass of an object, v is the speed, h is the height and g is acceleration due to gravity.

Substituting 19.7 Kg for mass, 0.934 for h, 2.93 for v and 9.81 for g then

Energy=19.7(9.81*0.934+0.5*2.93^{2})=265.063303\approx 265 J

What is meant by specific latent heat of vaporization of water is -2.26mjkg^-1 or -2.26mj/kg?​
Otrada [13]

Answer:

The specific latent heat of a substance is the amount of energy required to change the state of one kilo of the substance without change in it temperature.The latent heat of vaporization or evaporation is the heat given to some mass to convert if from the liquid to the vapor phase.
