Homework Statement
A 400 nm light ray is traveling through a vacuum.
a.) Give the light’s speed, frequency and color.
speed = 3E8: Correct
frequency = 7.5E14: Correct
color = violet: Correct
b.) This light now passes into a material where n=1.6. Give the light’s speed, frequency, wavelength and color in this new medium.
speed = 187.5E6 m/s: Correct
frequency = 750E12 Hz: Correct
wavelength = 250 nm: Correct
color = no longer visible light: Your answer is incorrect.I thought visible light only goes from 400nm to 700nm--What am I missing?
The other options are ROYBV
