I am a Biochemistry major on the pre-med track at Baylor University. I currently offer private tutoring and have tutored over 25 different students in all areas of STEM. My favorite subject is chemistry, but I am comfortable tutoring in almost any STEM field. I love helping other people to better understand their materials and to enhance their learning experiences.
State the second law of thermodynamics. How does the second law explain why heat travels from a substance at higher temperature to one at lower temperature?
What are the units for wavelength and frequency of electromagnetic waves? What is the speed of light in meters per second and miles per hour?
Give the high and low wavelength values that define the visible region of the electromagnetic spectrum.
Give two everyday examples that illustrate the concept of quantization.
(a) What is the frequency of light having a wavelength of $456 \mathrm{nm} ?$ (b) What is the wavelength (in nanometers) of radiation having a frequency of $2.45 \times 10^{9} \mathrm{Hz} ?$ (This is the type of radiation used in microwave ovens.)
How many minutes would it take a radio wave to travel from the planet Venus to Earth? (Average distance from Venus to Earth is 28 million miles.)
