GCSE Physics (9-1) - GCSE Physics - Visible Light & Colour - Colour Spectrum | Colour Filters (2026/27 exams)

⭐️ Check out our website https://www.cognito.org/ ⭐️ *** WHAT'S COVERED *** 1. The spectrum of colours in visible light * The relationship between colour, wavelength, and frequency. * An explanation of white light as a combination of all colours and black as the absence of light. 2. Why objects appear the colour they do * How absorption, reflection, and transmission of light determine an object's perceived colour. * The differences between how opaque, transparent, and translucent objects interact with light. 3. How colour filters work * How primary colour filters transmit specific wavelengths of light. * How secondary colour filters transmit a combination of primary colours. *** EXAM BOARD INFO *** AQA - Separate/triple science only IGCSE Edexcel - Don't need to know the details of this video, only for general interest Edexcel - Separate/triple science only OCR 21st Century - Separate/triple science only OCR Gateway - Separate/triple science only *** CHAPTERS *** 0:00 Introduction to Colour in Physics 0:23 The Spectrum of Colours in Visible Light 1:47 Why Objects Appear Coloured: Absorption, Reflection, Transmission 2:11 Opaque Objects and Colour Reflection 2:57 Transparent Objects and Colour Transmission 3:30 Translucent Objects and Scattering Light 4:15 How Colour Filters Work 4:28 Primary Colour Filters Explained 5:19 Secondary Colour Filters Explained *** PLAYLISTS *** https://youtube.com/playlist?list=PLidqqIGKox7VzYfPIVt8T09xOLNcolCe4&si=8JmDajxjtba6rdc3 https://youtube.com/playlist?list=PLidqqIGKox7UZ3mWhbHv2aA_1vnbsfRPq&si=q3hEKdA4v7kbfwMe https://youtube.com/playlist?list=PLidqqIGKox7XPh1QacLRiKto_UlnRIEVh&si=orIUwL3o2jOoiYjT https://youtube.com/playlist?list=PLidqqIGKox7X5UFT-expKIuR-i-BN3Q1g&si=DcihOwUkd9oWbbdp https://youtube.com/playlist?list=PLidqqIGKox7WeOKVGHxcd69kKqtwrKl8W&si=Y8MsO-FK948jnxpS https://youtube.com/playlist?list=PLidqqIGKox7UVC-8WC9djoeBzwxPeXph7&si=-7i5Iq7yOeJrhtu6 https://youtube.com/playlist?list=PLidqqIGKox7VKJD2WxRhoKaI6JGLVean8&si=NH_Q1ujhVgACM2FU #GCSE #Physics #study #revision #school #exam #AQA #OCR #Edexcel #IGCSE
