Tcecarenko [31]

Answer:

160.43 meters

Explanation:

T=(2*pi*r)/v

840=(2*pi*r)/1.2

1008=2*pi*r

504=pi*r

160.43=radius

A jewellery shop owner has two identical clear gemstones but cannot remember which one is diamond and which one is rutile. Rutil

pantera1 [17]

We know

$\boxed{\sf n_{21}=\dfrac{C}{V}}$

How he find:-

The owner will measure speed of light through the index(Diamond or rutile).Then using calculations he fill find which is the velocity of diamond or rutile

<h3> For diamond</h3>

$\\ \sf\longmapsto n_D=\dfrac{C}{V_D}$

$\\ \sf\longmapsto 2.4=\dfrac{3\times 10^8ms^{-1}}{V_D}$

$\\ \sf\longmapsto V_D=\dfrac{3\times 10^8ms^{-1}}{2.4}$

$\\ \sf\longmapsto V_D=1.25\times 10^8ms^{-1}$

$\\ \sf\longmapsto V_D=125\times 10^6ms^{-1}$

<h3>For rutile</h3>

$\\ \sf\longmapsto n_R=\dfrac{C}{V_R}$

$\\ \sf\longmapsto V_R=\dfrac{C}{n_R}$

$\\ \sf\longmapsto V_R=\dfrac{3\times 10^8ms^{-1}}{2.9}$

$\\ \sf\longmapsto V_R=1.03\times 10^8$

$\\ \sf\longmapsto V_R=103\times 10^6ms^{-1}$
