Diffraction grating experiment, wavelength determination, spectrometer, mercury lamp

This is a complete and detailed experiment about diffraction grating to find the wavelength of light using a mercury lamp (white light source).
Poits explained:
Diffraction grating
Spectrometer parts, adjustments
grating table, grating stand, telescope, collimator,
sodium vapour lamp, slit arrangement, spirit level,
journal, readings, observations, table, formula, calculations, result, diagram, practical.

[@SatyamSingh-xf6bc]

Very well explained
Giving feel of real practical lab

[@SSPhysics]

Instead of white light mercury source you can use monochromatic light source like sodium vapor lamp also to find out its wavelength with the same method.

Thank you so much sir you make my work more easier and next time whenever i am be in the lab i hope i would perform my experiment very effectively

[@shashikaladevi7761]

Very very very very very very very.......∞ times thank u 😌😌

[@shivanisule9975]

Very nice explanation👍👌👌

[@vishvasmeena4992]

Very helpful sir

[@axaanshkotadiya]

Sir, can we perform diffraction and YDSE experiment at home using ordinary objects used in daily life.
Bahut maza aata he jab science practically nazar aata he

Well explained sir♥️

[@sagarsinghi7]

Thank you sir

To calculate a+b u wrote 2.54 from wer it comes?

[@SSPhysics]

1 inch = 2.54 cm

[@tanmayraut3099]

Very nice sir

[@SumitKumar-fz3gq]

Thank you sir 🥰

[@ajeetkumarsharma888]

Thankyou sir

[@poornimadandu8946]

we should not rotate grating table to make grating element normal to mercury lamp or colarimeter

[@poornimadandu8946]

how we get 2.54 sir

[@mahibutt3095]

Values to likhi nhi table mein...naiki krni ho to puri b kia kro darya mein na daal diya kro

[@user-sy5fp4sc8b]

Please pdf ❤

Sur notes snd kr dn

[@SSPhysics]

Any doubt???🤔

[@janutenepalli2585]

When the distance b/w laser and grafting is short the we observe bright in screen but when it's long the bright will less!what is the reason ?

[@SSPhysics]

@Janu Tenepalli
Distance increases intensity decreases.
