Electromagnetic spectrum: wavelengths and thermometer effect
Fragen in diesem Quiz (2)
1Explain the effect on a thermometer of putting it into the ultraviolet part of the spectrum
- AThe thermometer went high
- Bthe thermometer would not record high temperature due to the fact that the light at that part of the spectrum has a short wavelength and high frequency.
- CIt was really low
2The waves in the visible spectrum have wavelengths between 380 and 750 nm, and frequencies between 400 and 790 THz.
(a) State a wavelength and a frequency of red light.
(b) Estimate a wavelength and a frequency of green light.- Athe frequency of red light would be 400 THz the wavelength of red light would be 750 nm
Wavelength of green light = (380 + 750)/2= 565 nm
The frequency of green light = (400 + 790)/2= 595 TH2 - BWavelength of green light = (382 + 754)/2= 565 THz
The frequency of green light = (420 + 7930)/2= 595 nm - COther
- Athe frequency of red light would be 400 THz the wavelength of red light would be 750 nm
