Different colors of light have different wavelengths but not different frequencies? True or False? Why?

Answer 1

False! Any change in wavelength equals a change in frequency.

Frequency = 3^5 / Wavelength

If wavelength increases, frequency decreases.
If wavelength decreases, frequency increases

Answer 2

False, different colors of light have different frequencies and different wavelengths.

The reason for this is because of the mathematical relationship between frequency and wavelength:

c = f*w

c is the speed of light, f is the frequency and w is the wavelength. Taking a quick look at the units should convince us:

f = cycles per time (really just 1/seconds, or "inverse seconds")
w = length (meters)
c = length/time (a speed!)

When you multiply the units inverse seconds times meters you get a speed expressed in meters per second. In vacuum, you should see that multiplying the frequency of light times the wavelength will always equal the speed of light (roughly 3*10^8 m/s)

Answer 3

False. Frequency is speed divided by wavelength. Since the speed of light is always the same, if the wavelength changes, so does the frequency.

Answer 4

All wavelengths of light travel at the same speed (in a vacuum) and the speed divided by the wavelength is the frequency.

So what do you think?

Answer 5

False. Because the speed of light is constant, if you increase the wavelength, you must decrease the frequency and vice versa.

Answer 6

False.
The wave length determines the frequency. When you add a time frame then wave length becomes a frequency. Frequency is Latin for "how often". How many waves pass a given point in a given time. The longer the length the lower the frequency because it takes a longer wave more time to pass that point. The shorter the length then the higher the frequency because more waves will pass that point in the same amount of time.

Answer 7

False
