In a diffraction pattern, what does the intensity of the central maximum depend on?
Correct Answer: Wavelength of light and slit width
- Step 1: Understand what a diffraction pattern is. It is a pattern created when light passes through a narrow opening (slit) and spreads out.
- Step 2: Identify the central maximum. This is the brightest part of the diffraction pattern, located in the center.
- Step 3: Recognize that the intensity of the central maximum is how bright it appears.
- Step 4: Learn that the intensity depends on the wavelength of light. Different colors (wavelengths) of light will create different intensities.
- Step 5: Understand that the slit width also affects intensity. A wider slit allows more light to pass through, increasing the intensity.
- Step 6: Conclude that both the wavelength of light and the width of the slit are important factors that determine how bright the central maximum is.
