For both, refractive index and Cauchy constants, the value obtained are higher in virgin olive oil as compared to virgin coconut oil. Data security: Varying degrees of security can be set, which include electronic signature and audit trail (not Abbemat 200). Usually the Refractive index of the water is taken as 1.33 and of oil is 1.58. so you can clearly see that the RI of oil is higher than that of water. 0000005692 00000 n Marketing cookies are used by third parties or publishers to show you personalized advertising. 0000001487 00000 n We use cookies on our website. _j 8Opp1p�r�20�Uzf��pj3(��ڻ�N�N�25*�x��Bo��L����%����1;��#��7)l6T��҉`�s�\f?���r�&�vtt4�Y�P�FGX�L B8i�I��LP���@ �����X,� Essential oils such as lemon or orange oil are also referred to as volatile oils. x���A 0ð4t�y\Gcw��������z�C. 0000057942 00000 n 0000002160 00000 n 0000010234 00000 n 1289 0 obj<>stream Here you can find an overview of all used cookies, get detailed information, and decide which cookie types to accept.
