In the draft amendments of the Food Safety and Standards (food Products Standards and Food Additives) Amendment Regulations 2019, the refractive index parameters had been proposed to be amended which were as follows. �}E.

(A plano concave lens is formed between plane mirror and convex lens). In the Food Safety and Standards (Food Products Standards and Food Additives) Regulations, 2011 under the regulation 2.2: FATS, OILS AND FAT EMULSIONS in the category 2.2.1 OILS for the standards of coconut oil the parameter Refractive Index has been amended from the following, Refractive Index at 40oC:       1.4481-1.4491, Refractive Index at 40oC:     1.4480-1.4500. New Delhi, India-110015, Copyright © 2020 Auriga Research Pvt. Refractive Index: Refractive index is a way to classify and describe how light travels through a substance. This property has enabled the efficient use of liquid lens to find the refractive index of a fluid by this method. Refractive Index . The refractive index of coconut oil is 1.43-1.46. In optics, refractive index or index of refraction ‘n’ of a substance (optical medium) is a dimensionless number that describes how light or any radiation propagates through that medium.It is defined as. The draft regulations are in the process of being notified but the process of notification, the consideration of comments received by the FSSAI and the finalisation of these regulations is likely to take some time. However, inorder to address the issue of the food business operators to comply with the present standards of coconut oil for the said parameter and to harmonise with the international standards – Codex, it has been decided to implement this parameter with immediate effect. ); for many … Refractive index can also help to differentiate between the various oils and also to differentiate between different fats like butter and margarine. • The lens and plane mirror should be cleaned thouroughly. I think buddy that this answer will help you. In this project, we shall make use of the property of liquid lens to find the refractive index of water and coconut oil. Let it be x2. Notre Dame president caught in WH coronavirus storm. The radius of curvature 'R' of the lens is given by. • Bring the tip of the needle, at the vertical principal axis of the lens, so that the tip of the needle appears touching the tip of its image. The experiment described in this project is an effective and simple method of measuring the refractive index of any liquid (transparent) using a convex lens and plane mirror. stream .�0d�з&Ob΍L���pn{U���.qw앒NF�͗�����Hx؎ڈ�����V�Bsݓ�M�8���&}s�8ē��� >��fS]�׹h��,qփ �[Umʓ� �݁pQ�J��ʇJ�+k*��g��wm��6T� ��������֛\y�{/�^_Uz�� H:7���.0�b%6\���J���\�x@ؖp�·A��p'��I0^~��э�[H�� ���a�۶�){=�L>�ʊ���^n�0���+Ϭ�&���Y��Nؤ1��G��Z��G� $h�_�:����Y��eruc���]����N�]d��~V���xV�Ű���3[x�_����~��o� �"\�VF,�G�W�>^����^�0q��[q��/��!2�"���9��L�#��&�,�9�����{? The theory behind liquid lens is based on the properties of one or more liquids to create magnifications within a small amount of space.The focus of a liquid lens is controlled by the surface of the liquid .Water normally forms a bubble shape when … The convex lens is placed over it as before. FBOs who manufacture coconut oil will have to comply with these amended parameters with immediate effect. Refractive Index at 40 o C: 1.4481-1.4491. Aim is to find the refractive index of a) water, b) coconut oil using a plane mirror, and an equiconvex lens made of glass and an adjustable object needle. St. Louis couple indicted for waving guns at protesters If a liquid is sandwiched between the lens and the mirror, the focal length of liquid lens can be calculated knowing the focal length of the combination and that of the convex lens, from which the refractive index of the fluid can easily be estimated .
