A beaker containing a liquid is left to sit undisturbed overnight. In the morning, there are no particles on the bottom of the beaker. When the liquid in the beaker is stirred and filtered there are no particles on the filter paper. If a laser beam is aimed at the beaker a line of light across the liquid appears. The liquid does scatter light. The beaker contains a…

Word bank Type the words exactly as written wave, quanta, frequency, energy, speed of light, wavelength, photon Electromagnetic radiation is a kind of type your answer. that behaves like a type your answer. as it travels through space. At the same time, it also behaves like a particle called a type your answer. These particles contain a type your answer. of energy that is related to the wavelength of the light. All waves can be characterized by their wavelength, frequency, and energy. The distance between troughs on a wave is called the type your answer. The number of waves that pass a given point in one second is the type your answer. All waves travel at the type your answer. in the vacuum of space
