I am a high school student so please apologise if I say something very dumb or irrelevant. I am conducting an experiment in which I want to find UV index at different points. Such as under shade, inside house, near beach etc. Anything will be greatly appreciated, also even if there is a device thats very expensive please tell me about that as well.

Finding 'UV index' at a point might be difficult. UV index is an index created by I think was WHO, and is calculated using - Thickness of ozone above - Cloud density of the area - Altitude of location - Sun's height more about it here - https://www.who.int/uv/publications/en/UVIGuide.pdf So I think you are better off finding the UV light intensity instead, using some measurement tools. There's few different options like photo reactive dyes, and digital scales, but probably the most cheap and quantitative data can be obtained using arduino or other similar development board and creating a small module yourself. Good Luck!
