Document Summary
Short answer : psychophysical methods: signal dectection theory, method of limits, method of adjustement, magnitude estimation, cross modality, method of constant stimuli, Light: electromagnetic waves, it is a tiny particle depends on the situation. Easier to talk about light as particles so photons when they hit something and are absorbed. Longer wavelengths are the realm of visible lights. Light can be absorbed: energy is taken up and not transmitted anywhere else ex: dust, red light passes through any other color doesn"t. Diffracted: waves spread out or bend in water for ex. Reflecting: happens on the eye, on the retina, it is redirected when it strikes a surface. Transmitted: ex a solar panel, energy is encountering the surface and transmitted in some form, it passes through and changed into another energy with solar panels is electrical energy. Refraction: how energy is altered as it passes through another medium (ex: put pool stick in pool it looks bent) ex: rainbow prism.
