The above diagram shows a beam of monochromatic X-rays incident at a glancing angle. It may be noted that in optics, we measure incident angle as well as reflected angle between the ray and normal drawn to the plane. But Bragg measured these angles between the ray and the plane itself, and it is called as Bragg’s angle. The X-ray beam partially reflects and refracts from different planes of the NaCl crystal at A, B, C etc. The paths of rays until A and M and also until A and N are equal. If we compare the total paths of two rays (R1, R2), ray2 takes an extra path of MB and BN. By drawing perpendiculars AM and AN, we can calculate the path difference between two rays. Path difference = MB + BN From the two triangles AMB, ANB we know that sin = MB/AB = MB/d Or MB = d sin Similarly, sin = BN/AB = BN/d Or BN = d sin Now path difference = d sin + d sind sin

Neat village station.All Passenger trains stops here. One express train only stops here.

A small railway station in Kanyakumari district. Only few shops r available here. Surrounded by windmills & mountains all around.

Another small halt on the Madurai Nagercoil route if the Southern Railway. Picturesque and scenic, surrounded by banana plantations, lush green fields, canals and windmills, it's truly a sight for sore eyes... There are only two platforms with the basic amenities. Well-maintained and very clean. There are benches and a small waiting area and covered areas for inclement weather...

Near Tirunelveli town, there is lot of wind mill producing electricity commercially, the place covered by western ghats and good natural beauty.

Panakudi is a panchayat town in Kanniyakumari District in the state of Tamil Nadu, India. It is a small town situated in southern India. The town was earlier called as Aramboly during colonial period. small railway station not all train stopping this place.this place around on mountain and windmills amazing please to photo shoot.

The X-ray beam partially reflects and refracts from different planes of the
NaCl crystal at A, B, C etc. The paths of rays until A and M and also until A and
N are equal. If we compare the total paths of two rays (R1, R2), ray2 takes an
extra path of MB and BN. By drawing perpendiculars AM and AN, we can
calculate the path difference between two rays.
Path difference = MB + BN
From the two triangles AMB, ANB we know that
sin = MB/AB = MB/d
Or MB = d sin
Similarly, sin = BN/AB = BN/d
Or BN = d sin
Now path difference = d sin + d sind sin
