PPT-Wavelength, Frequency, and Energy Practice Problems

1 A certain violet light has a wavelength of 413 nm What is the frequency of this light 2 What is the wavelength of radiation whose frequency is 150 x 10 13 Hz 3 How much energy is associated with a photon in the microwave region of the spectrum with a frequency of 66 x 10. S8P4. Students will explore the wave nature of sound and electromagnetic radiation. . a. Identify the characteristics of electromagnetic and mechanical waves. . What are waves?. Waves carry energy. Rhythmic disturbances that carry energy without carrying matter are called waves.. SOUND IS…. (for our purposes). Movement of the air that happens at human hearing frequencies:. 20 - 20,000 cycles per second. The easiest case to imagine is a “monopole” sound source.. Imagine a ball suspended in the air that expands and contracts, pushing and pulling on the air around it.. many narrow, adjacent wavelength Plot Wavelength (micrometers) 0.00.20.40.62.21.71.20.7 A plot of the brightness valuesversus wavelength shows thecontinuous spectrum for theimage cell, which can be u Almost all of our information on the heavens is derived from the light we see. We have returned samples from the Moon and a comet . Also obtained meteor samples. We have landed (with unmanned probes) on only a handful of planets and moons. Vocabulary. Period: the time for one cycle of simple harmonic motion, or the time for a full wavelength to pass a position.. Frequency: the number of cycles, or the number of wavelengths passing a position, in one second. . Equations. On Equation Sheet. Planck’s Equation: . Wave Equation: . Beer’s Law: A = . abc. E = energy. = frequency. = wavelength. Planck’s Constant: h = 6.626 x 10. -34. . Js. Speed of light: c = 3 x 10. What is energy?. Make a list of the major forms of potential energy. Make a list of the major forms of kinetic . What do all mechanical waves need to exist?. Sketch a longitudinal wave. Label its parts. Draw an arrow to show how the energy moves through the wave.. 4 Basic Properties of Waves . Amplitude. Wavelength. Frequency. Speed. Amplitude . Maximum distance the particles of the medium carrying the wave move away from the resting place. Amplitude of Transverse Wave. WAVESUnit 10next to you discuss what this might beSECTION 1 THE NATURE OF WAVESA Wave a repeating disturbance or movement that transfers energythrough matter or space1 Molecules pass energy on to n Examples are cyanine dyes – Cy3 and Cy5 . There is a spectrum for excitation and emission for each molucule. . We want to observe light emitted at a wavelength separate from the excitation.. If the spectra of different molecules do not overlap too much we can use them together.. Measuring Waves: Variables Recap. Frequency. . ( f ). # of waves passing a point in 1 second. SI unit: Hertz (Hz). shorter wavelength .  higher frequency  higher energy. 1 second. Range for human hearing =. Chapter 1 section 2. Electromagnetic Spectrum.
