    How do you do these? Please show step by step Properties of Waves - Copy Learning Goal: To understand electromagnetic radiation and be able to perform calculations involving wavelength, frequency, and energy. Several properties are used to define waves. Every wave has a wavelength, which is the distance from peak to peak or trough to trough. Wavelength, typically given the symbol λ(lowercase Greek "lambda"), is usually measured in meters. Every wave also has afrequency, which is the number of wavelengths...

    Please answer question i thank you! h) (4 pts) Ebonite, from which bowling balls are made is one of the most triboelectrically active substances. The precise mechanism for the triboclectric effect is still very much a scientific mystery. The surface of bonite will quickly pickup excess electrons as it moves through air. Moving charges comprise an electric current Oscillating electric currents generate radio waves. If the muss used in this question is ebonite, its oscillations will generate radio waves that...

    question 7 and 8 Purpose To examine the properties of polarized light and the mathematical relationship describing the intensity of linearly polarized light (Malus'law). In addition, the lab will investigate different ways light can be polarized Overview This lab is the first of three labs exploring the properties of electromagnetic waves. Electromagnetic waves are composed of oscillating electric and magnetic fields. As discussed in the lecture the electric and magnetic field vectors are mutually perpendicular to each other. Light waves...
