O mankind! verily there hath come to you a convincing proof from your Lord: for We have sent unto you a light (that is) manifest. (Surah an Nisa174) . The elementary particle that defines light is the photon.. There are 3 basic dimensions of light. Intensity (amplitude) which is related to the perception of brightness. Frequency (wavelength), perceived as colour. Light. Science. . . Success Criteria. Aim. I can use a mirror to reflect light and explain how mirrors work. . I can explain why mirrors are good reflectors.. I can use mirrors to reflect light onto different objects.. Black is the absence of light.. This font is black because no light is shining here. . The light shines all around it making white. . Mixing colors. By mixing different colors you can create new colors..
