Questions & Step-by-Step Solutions
If the wavelength of light used in a double-slit experiment is increased, what happens to the position of the interference fringes?
Step 1: Understand that in a double-slit experiment, light passes through two slits and creates a pattern of bright and dark lines called interference fringes.
Step 2: Know that the position of these fringes depends on the wavelength of the light used.
Step 3: Recognize that if the wavelength of the light is increased, it means the light waves are longer.
Step 4: Realize that longer wavelengths cause the fringes to spread out more.
Step 5: Conclude that increasing the wavelength results in the interference fringes moving further apart from each other.
Interference Patterns – The behavior of light waves when they overlap, leading to constructive and destructive interference.
Wavelength and Fringe Width – The relationship between the wavelength of light and the spacing of interference fringes in a double-slit experiment.
