》) Activity 2 Test yourself Interpreting the electromagnetic spectrum 1 Here is a mixed-up list of the different types microwaves; visible light; X-rays; infrared ligh ultraviolet light Arrange them in order of a) increasing frequencies b) increasing wavelengths c) increasing energy. 2 Calculate the frequencies of these waves: a) a radio wave with a wavelength of 2 met b) yellow light with a wavelength of 600 nn c) an X-ray with a wavelength of \( 10^{-12} \mathrm{~m} \). 3 Calculate the wavelengths of these: a) a cell phone that sends frequencies of 2, b) ultraviolet light with a frequency of \( 10^{16} \) c) a gamma ray with the frequency of \( 10^{19} \)

Get ready to dive into the awesome world of electromagnetic waves! Did you know that the electromagnetic spectrum is like a big family where each wave has its own special place? From long radio waves to tiny gamma rays, they all vary in frequency, wavelength, and energy. For example, radio waves are on the low end of the frequency spectrum, while X-rays and gamma rays zip by at lightning speed with much higher frequencies. Such diversity means that different waves have different uses in our everyday lives, from cooking food with microwaves to scanning our bodies with X-rays! Now, here's a fun fact: the relationship between wavelength and frequency can trip some people up! Remember, as the wavelength gets longer, the frequency decreases—it's a seesaw effect! So, when solving those frequency and wavelength calculations, just keep in mind that higher energy radiation like X-rays will have shorter wavelengths compared to your everyday radio waves. Make sure to double-check your units to avoid any mix-ups—this is a common mistake that can lead to incorrect results. Happy calculating!
