"And At Last I See The Light!!!!!"
Although I've used this picture before, I feel like this is related to our unit on electromagnetic waves and color. To make a picture like this, you have to be in a dark room and use a flashlight and a DSLR camera. After turning the camera setting to "bulb", angle the flashlight towards the camera, press and hold the button, and then draw or write!
This demonstrates physics concepts in different ways! The flashlight is an example of a light emitter, (which is something that gives off light) and it travels in lines. In order for the light drawing to show up, the light from the flashlight needs to go to the lens. When the light is angled towards me and the camera, it creates a shadow, which is the absence of light, in the back of me. The light from the flashlight was a white light, which means that it has all the frequency of light (Red, Orange, Yellow, Green, Blue, Indigo, and Violet).
