SUMMARY

The discussion focuses on calculating the frequency of energy using Planck's constant, specifically for an energy value of 3.5 x 10^-14 joules. The relevant equation is E=hv, where E represents energy, h is Planck's constant (6.63 x 10^-34 joule-seconds), and v is the frequency in hertz (Hz). Participants emphasize the direct proportionality between energy and frequency, clarifying that as energy increases, frequency also increases. The calculation involves rearranging the equation to solve for frequency (v).

PREREQUISITES
  • Understanding of the equation E=hv
  • Familiarity with Planck's constant (6.63 x 10^-34 joule-seconds)
  • Basic knowledge of energy units (joules)
  • Concept of frequency in hertz (Hz)
NEXT STEPS
  • Practice solving problems using the equation E=hv with different energy values
  • Explore the implications of Planck's constant in quantum mechanics
  • Learn about the relationship between energy and frequency in electromagnetic waves
  • Investigate applications of frequency calculations in spectroscopy
USEFUL FOR

Students in physics, educators teaching quantum mechanics, and anyone interested in the relationship between energy and frequency in light and electromagnetic radiation.

Read my Journal nd hlp. calculating frequency

--------------------------------------------------------------------------------

I have a problem that states as follows:

Calculate the frequency (in Hz) of energy of 3.5 x 10^-14 joules. (c=3.00 x 10^8 m/s; h=6.63 x 10^-34 joule-seconds)

I need help in setting this problem up. I found the equation E=hv, where E= the increase of energy, h= Planck's constant, and v= the freqency of light which increases propportionally with an increase in energy.

I am going crazy and just don't get it...
