This is the second webinar of our two-part series on waves and will cover light. Light is an E/M and a transverse wave. Compared to sound, light is more content-rich and has already appeared in chemistry topics like Planck’s equation and UV-vis spectrometry. In this webinar, we will review the five properties of light, the polarization of light, the Doppler effect as applied to light, and the ever-confusing topic of optics in mirrors, lens and compound lens instruments like the microscope.
