When wavefronts pass from denser medium to rarer medium, the width of the wavefront
When wavefronts pass from denser medium to rarer medium, the width of the wavefront
increases.
may increase or decrease.
decreases.
remains unchanged.
Solution
- As the wavefronts move from the denser medium to the rarer medium, the distance between successive wavefronts increases.
- Therefore, the width of the wavefronts increases when transitioning from a denser medium to a rarer medium.
- The correct answer to the question is that the width of the wavefront increases when wavefronts pass from a denser medium to a rarer medium.
