What is the wavelength of light (Å) that has a frequency of 3.6×〖10〗^14 Hz?a.6.67〖×10〗^(-7)b.666.7c.1500d.6667

The approximate wavelength of Red light isa.3000Ǻb.7000Ǻc.3500Ǻd.100

The lowest wavelength of the visible light part of the spectrum occurs at about

One of Mr. Chowder's lab groups is staying after school to complete the Young's Experiment investigation. They observe that light through passing two slits travels 3.93 m to a screen to produce a pattern of bright and dark bands. The group measures the distance between the first and the second bright bands on the same side of the pattern to be 18.8 mm. The slits are spaced 0.132 mm apart. What is the wavelength (in nanometers) of the light source?Wavelengthnm

A UV/Vis spectrum shows an absorbance peak at 452 nma. What colour of the visible spectrum does this wavelength represent?
