spherometer experiment ( theory, formula and calculation-part 2)

In this video you can learn the derivation of theory, formula and calculation of spherometer experiment(part-2). The first part of spherometer experiment you get by clicking the following link:
• Spherometer experiment...
This video is useful for the standard- XI & XII. This is the part-2 of the practical ' To measure the radius of curvature of a given spherical surface(convex/concave) by using spherometer.'
For learning screw gauge / vernier calliper click on the following link:
• To measure the diamete... - vernier calliper
• To measure the diamete... - screwgauge
• To measure the diamete... - screwgauge

Thanks again for down to the root explanation. This has been one of the best and thorough explanation I have seen.
One question...
Do you take the readings (10 readings from your previous video) from different points on the surface or do you concentrate the readings around the center of the watch glass?
I am using your knowledge and explanation to find the radius of curvature of my primary mirror of my telescope and from that calculate focal length.
Really appreciate this down to the bones explanation. Excellent video

[@samarthaggarwal3470]

I'm not sure if it'd make a difference either way but I don't know

[@RuhulalamChoudhury]

Khub bhalo.... Really nice video

How is that AO in the 2D sphere = AO in Equi. Δ, Do we have to use projection concept for understanding this equality?

Mam whether the spherometer's middle leg should be at the centre of the curved surface or at random

[@behindthecurtains7582]

Does not matter. The answer will not vary.

Amazing work mam👍👍

This Spherometer is not a physics lab device, it's mechanical metrology lab device used for calculation of radius of spherical dome (sector) which you are calling it as curvature.

Mam please do simple pendulum one practical

[@behindthecurtains7582]

I will try.

[@gowthami9304]

Madam can you please explain how cos 30 has came ???

[@behindthecurtains7582]

Because it forms a equilateral triangle generally. so half of the angle is 30 degree.

[@snigdhamaji7457]

Please

[@snigdhamaji7457]

And mam please can you explain me the pendulum experiment also

Mam why there is no error in spheromoter?

[@behindthecurtains7582]

Yes there can be error in spherometer like back-lash error.
