Wavelength question?

Question

A wave's frequency triples. By what factor is its wavelength changed?

Answer:

a. three

b. one (no change)

c. one third

d. one ninth

Answer 1

a

Answer 2

A.  When you triple the frequency of the waves, you reduce the wavelength by a factor of three.  

Answer 3

The relationship between frequency and wavelength is given by the formula c = frequency x wavelength

Therefore frequency = c / wavelength i.e. wavelength is inversely proportional to frequency.

So, as frequency x 3, wavelength x 1/3

Answer is c

Answer 4

If frequency triples, wavelength will become one third (c).
