Find the sound's wavelength (λ) and frequency (f) in the medium. Multiply the sound's wavelength by its frequency to obtain the speed of sound (v): v = λ ⋅ f. Verify the result with our sound wavelength calculator.
This is Omni's wavelength to energy calculator, a tool that instantly calculates a photon's energy from its wavelength. By using Planck's equation, this tool will help you determine a photon's energy in joules (J), electronvolts (eV), or its multiples.
1. A wave with a frequency of 14 Hz has a wavelength of 3 meters. At what speed will this wave travel? 2. The speed of a wave is 65 m/sec. If the wavelength of the wave is 0.8 meters, what is the frequency of the wave? 3. A wave has a frequency of 46 Hz and a wavelength of 1.7 meters. What is the speed of this wave? 4.
More Practice: Energy, Frequency, Wavelength and the Photoelectric Effect. There are two equations you should know: E = h! and c =!!" !=!!!!!∴!!!=!!! E = energy (J) = wavelength (m) ! = frequency (Hz or s-1) h = Planck’s constant, 6.626x10-34 J∙s c = the speed of light in a vacuum, 3.00 × 108 m∙s-1
30 Ιουλ 2024 · You can find a few typical wave velocity values below. Type them into our wavelength calculator to learn what is, for example, the wavelength of red light in water. Light in air or vacuum: 299,792,458 m/s; Light in water: 224,901,000 m/s; Sound in air: 343.2 m/s; Sound in water (20 °C): 1,481 m/s
What is the wavelength of the radio signal? 2.78 × 106 m. 9. If the limits of human hearing are 20 Hz. to 20,000 Hz, what are the sound wavelengths that are associated with both of these two extremes, assuming the speed of sound is 345 m/s. Frequency = 20 Hz : Wavelength = 1.725 × 101 m.
Chemistry Worksheet and Answers Wavelength, frequency, & energy of electromagnetic waves. C = λν. C = 3.00 x 108 m/s. E = hν h = 6.626 2 x 10-34 J-s (or J/Hz) 1. What is the wavelength of a wave having a frequency of 3.76 x 1014 s-1?
