i need help with these questions, maybe i can get a website or something to help me.

what is light is. what makes different types of electromagnet radiation different from each other. how electromagnetic radiation is used in everyday life. what is color.

different ways light is produced. label a diagram of a light ray reflecting off a plane mirror. Provide example. how to measure the angle of incidence and the angle of reflection. two parts of the law of reflection. find an image in a plane mirror using the laws of reflection. Provide example. find images in converging and diverging mirrors using ray diagrams. Provide examples for each. SALT the images I find in converging and diverging mirrors. real life uses of both types of curved mirrors. what is refraction. why refraction occurs. can predict if a light ray will bend towards or away from the normal. know and can use the formula for the index of refraction (both versions). can describe real life experiences with refraction (mirages, apparent depth...). know what a critical angle is. know what happens when the angle of incidence is larger than the critical angle. know the conditions that need to be met for total internal reflection to occur. can describe real life examples of total internal reflection (fibre optics, periscopes...). can draw ray diagrams to locate images with converging and diverging lenses. Provide examples of each. can SALT the images created by lenses. know some everyday applications of lenses. (Example) know and can use the thin lens equation. (Example) know and can use the magnification equations. (Example)
