P1 Topic 2: The Electromagnetic Spectrum This topic looks at: The waves in the electromagnetic spectrum with a description The uses and danger of electromagnetic waves Add the different waves onto the electromagnetic spectrum with their uses: What is the speed of light in a vacuum? There are 2 types of waves describe each of them below: Longitudinal Transverse Which are the waves found in the electromagnetic Spectrum How do we know electromagnetic waves can travel through a vacuum such as space? Ionising Radiation What is ionising radiation and what are the three type of ionising radiation? Ionising Radiation = 1. 2. 3. Using the wave equation calculate the following v=fλ (hint use the speed of light) What is the frequency of a wavelength 40m What is the frequency of a wavelength 35cm What is the wavelength of a wave with a frequency of 450 Hz What is the wavelength of a wave with a frequency of 320Hz KeyWords: Alpha, beta, gamma, ionising, DNA, skin cancer, mutation State Dangers of each of the electromagnetic waves below: Keywords: ionising, radioactive, ions
