Answer:

Normally, light travels in a straight path called a ray, however, when passing through clear materials, like water or glass, light bends or turns. As a result, the direction and speed of the traveling light wave will change and the light will appear to bend or change directions.

(Hope this helps!! Btw, I am the first answer.)

You illuminate a slit with a width of 71.7 μm with a light of wavelength 737 nm and observe the resulting diffraction pattern on

miskamm [114]

To solve this problem we will apply the concepts related to the double slit-experiment. Under this concept we understand the relationship between the minimum angle, depending on the order of the fringes, the wavelength and the distance between slits. Therefore we have the following relation,

$sin(\theta_{min}) = \frac{m\lambda}{D}$

Here,

m = Order of the fringes

D = Distance between slits

$\lambda$ = Wavelength

Replacing with our values we have,

$sin(\theta_{min}) = \frac{(1)(737*10^{-9})}{71.7*10^{-6}m}$

$sin(\theta_{min}) = 0.01028$

Through the relationship between distances then we have that the basic amplification distance is given by the relationship between the distance of the slit L and the angle, then

$Y=Lsin\theta$

$Y =2.27*0.01028$

$Y =0.0233m$

Thus the width of the central maximum is

$W=2Y=2*0.0233$

$W = 0.0466m$

Therefore the widht is 0.466m

An apparatus like the one Cavendish used to find G has large lead balls that are 8.4 kg in mass and small ones that are 0.061 kg

garik1379 [7]

Answer:

The gravitational force is $1.05\times10^{-8}\ N$

Explanation:

Given that,

Mass of large ball = 8.4 kg

Mass of small ball = 0.061 kg

Separation = 0.057 m

Gravitational constant $G= 6.67\times10^{-11}\ Nm^2/kg^2$

We need to calculate the gravitational force

Using formula of gravitational force

$F= \dfrac{Gm_{1}m_{2}}{r^2}$

Put the value into the formula

$F=\dfrac{6.67259\times10^{-11}\times8.4\times0.061}{(0.057)^2}$

$F=1.05\times10^{-8}\ N$

Hence, The gravitational force is $1.05\times10^{-8}\ N$

A naturally occurring force related to two bidies in motion is force

1. Frictional force

A naturally occurring force related to two bodies in motion is frictional force. Friction is a type of force which includes two bodies resisting each other –either motion of solid surfaces, fluid layers, material elements and compounds gliding against each other. They key point of this frictional force is that the two forces are in the opposite point of direction with each other. For example, when you are cold, as you rub your hands together notice that when your right hand is going upward, your left hand is downward and thus creates heat. That is one type of friction force outcome, the heat.
