Answer:

D. A and B

Explanation

as frequency is inversely proportional to wavelength. formula for calculating wavelength is  

wavelength = wave velocity/frequency.

as wavelength is inversely proportional so increase in wavelength will cause decrease in frequency and vice versa . so A and B are the right answer.

Answer:

A and B

Explanation:

For an electromagnetic wave, the relationship between frequency and wavelength is given by:

[tex]\lambda\times\nu=c[/tex]

where [tex]\lambda[/tex] is wavelength

           [tex]\nu[/tex] is frequency

           and c is speed of light.

From the formula we can say that frequency is inversely proportional to the wavelength as speed of light is a constant.

Hence

  • As frequency increases wavelength gets shorter.
  • As frequency decreases wavelength gets longer.
