A beam of white light is dispersed by a prism into a spectrum of seven colors. Complete the list below to show the five missing colors of the visible spectrum in order, from the longest wavelength (next to Red) to the shortest wavelength (next to Violet).
Red, ‾,‾,‾,‾,‾, Violet \text{Red, } \underline{\quad\quad\quad}, \underline{\quad\quad\quad}, \underline{\quad\quad\quad}, \underline{\quad\quad\quad}, \underline{\quad\quad\quad}\text{, Violet} Red, ,,,,, VioletDifferent regions of the electromagnetic spectrum have different uses. Identify the correct type of radiation for each of the following applications:
Choose from: radio waves, microwaves, infra-red, visible light, ultraviolet, X-rays, gamma rays.
All electromagnetic waves travel at the same speed in a vacuum. Complete the following sentence using a word from the box below:
amplitudefrequencyspeed \begin{array}{|ccc|} \hline \text{amplitude} & \text{frequency} & \text{speed} \\ \hline \end{array} amplitudefrequencyspeed"The position and classification of each type of radiation in the electromagnetic spectrum is determined by its " ‾\underline{\quad\quad\quad\quad\quad\quad}.
