SUMMARY

This discussion focuses on comparing the wavelength and frequency ratios of visible light to radio light. The specific wavelengths mentioned are 700 nanometers for red light and 400 nanometers for violet light, with corresponding frequencies of 4.29 x 1014 Hz and 7.5 x 1014 Hz, respectively. For radio light, the wavelength is 555 meters (frequency of 540 kHz) and for microwaves, the wavelength is 12 cm (frequency of 2.5 x 109 Hz). The primary task is to calculate and compare the ratios of these wavelengths or frequencies.

PREREQUISITES
  • Understanding of wavelength and frequency concepts in physics
  • Familiarity with the electromagnetic spectrum
  • Basic mathematical skills for ratio calculations
  • Knowledge of units of measurement (nanometers, meters, centimeters)
NEXT STEPS
  • Research the electromagnetic spectrum and its various regions
  • Learn about the mathematical principles behind ratio calculations
  • Explore the properties of light and its interaction with matter
  • Study the differences between AM radio and microwave frequencies
USEFUL FOR

Students studying physics, educators teaching about light and the electromagnetic spectrum, and anyone interested in the properties of light and radio waves.

Ok so I am not sure how to do this problem the only equation i am familiar with that might have to do with it but I am not so sure it is used on this problem the equation is dsin(-)=wavelength

the question is

2.Compare the wavelength or frequency range of the visible light our eyes can see to the range of radio light. Red wavelength = 700 nanometers, frequency = 4.29 x 1014 Hz Violet wavelength = 400 nanometers, frequency = 7.5 x 1014 Hz Radio (AM radio) wavelength = 555 m, frequency = 5.4 x 105 Hz (540 kHz) Microwave (microwave oven) wavelength = 12 cm, frequency = 2.5 x 109 Hz What is the ratio of red to violet light compared to the ratio of AM radio to microwaves? Give the ratios for either wavelength or frequency.

thank you!

It's just a ratio problem. How does the ratio (700 nanometers)/(400 nanometers) compare to the ratio of (555 m)/(12 cm)? That's all.
 
o ok thank you
