Calculate the wavelength (in nm) of light that produces its first minimum at an angle of 21.0° when falling on a single slit of
Cerrena [4.2K]

To solve this problem it is necessary to apply the related concepts to the principle of overlap, specifically to single slit diffraction experiment concept.

Mathematically this can be expressed as:

dsin\theta = m\lambda

Where,

d = Width of the slit

\lambda =Wavelength

\theta = Angle relative to the original direction of the light

m = Any integer which represent the order of the equation (number of repetition of the spectrum)

To solve the problem we need to rearrange the equation and find the wavelength

\lambda = \frac{dsin\theta}{m}

Our values are given as,

d = 1.46\mu m = 1.46*10^{-6}m

\theta = 21\°

m = 1

Replacing in our equation we have,

\lambda = \frac{dsin\theta}{m}

\lambda = \frac{(1.46*10^{-6})sin(21)}{1}

\lambda = 5.232*10^{-7}m

\lambda = 523.2nm

Therefore the wavelength is 523.2nm

What is the best thermal insulator? aluminum copper steel or glass
anyanavicka [17]

Answer:

Copper is a better heat conductor than glass. In general, we think of metals as good conductors. In fact, metals vary widely in their conductivity but, overall, they are better conductors of heat than most liquids and gasses. Other solids also vary in their capability to conduct heat.

Examine the information. A truck accelerates 3 km/h/s south. Which option correctly describes the truck’s acceleration?
Oksanka [162]

Answer:

d. Every second, the truck’s velocity increases by 3 km/h to the south.

Explanation:

Acelleration can be defined as change of velocity over change of time.

That's why if we say:  "A truck accelerates 3 km/h/s south."

We are saying that the acceleration of the truck variate 3Km/h wich is  velocity of the truck, and it variates every second and also its direction is south.
