Adiffraction grating with 750 slits per mm is illuminated by light which gives a first-order diffraction angle of 34.0°. what is the wavelength of the light?

Explanation:

The diffraction angles when we have a slit divided into parts are obtained by the following equation:

(1)

Where:

is the width of the slit

is the wavelength of the light  

is an integer different from zero

Now, the first-order diffraction angle is given when , hence equation (1) becomes:

(2)

We know:

In addition we are told the diffraction grating has 750 slits per mm, this means:

Solving (2) with the known values we will find :

(3)

(4)

Knowing :

 >>>This is the wavelength of the light, wich corresponds to red.

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
