Question

Why is the ratio of the velocities of light of
wavelengths 4000 "Å linel 2000 Å in vaccum 1:1
Which of the above wavelength has a higher
frequency​

Answer 1

Answer:

Since light is an electromagnetic wave and it is the property of all the electromagnetic waves that they travel with same speed equal to 3×10

8

m/s in vacuum. Hence ratio of velocities of light of wavelength 4000 A

o

and 8000 A

o

in vacuum is 1:1...

hence.....4000 A° will have higher frequency......
