Adiffraction grating produces a first-order bright fringe that is 0.18 m away from the central bright fringe on a flat screen. the separation between the slits of the grating is 2.5 x 10-6 m, and the distance between the grating and the screen is 0.8 m. what is the wavelength of the light shining on the grating?

The wavelength of the light is 562.5 nm

Solution:

As per the question:

Order, n = 1

Slit separation, d =

Distance from the bright fringe, y = 0.18 m

Distance between the screen and the grating, D = 0.8 m

Now,

We know from the eqn for diffraction:

n = 1

           (1)

Also,

For very small angle, :

≈

Using the above value in eqn (1):

unlike poles attract

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
