To increase resolving power, use a lens with higher numerical aperture or increase the wavelength of light used. To increase diffraction power, decrease the wavelength of light or use a lens with a shorter focal length. Balancing these factors will optimize the overall imaging performance.

Does diffraction only happen in transverse waves?
No, diffraction can occur in both transverse and longitudinal waves. Diffraction refers to the bending of waves around obstacles or through openings, regardless of the wave orientation.
What are the two types of diffraction?
The two types of diffraction are Fraunhofer diffraction, which involves light rays that are parallel before and after passing through the diffracting object, and Fresnel diffraction, which occurs when the light source and the screen receiving the diffracted light are at a finite distance from the diffracting object.
How many types of diffraction are there?
There are two main types of diffraction: Fraunhofer diffraction, which occurs in the far field of a diffracting object, and Fresnel diffraction, which occurs in the near field. Both types involve the bending of waves around obstacles or edges, resulting in the spreading of the wavefront.
Is optical grating and diffraction grating same?
Yes, optical grating and diffraction grating are the same. They both refer to a carefully engineered surface with regularly spaced grooves that can disperse light into its spectral components through the phenomenon of diffraction.
What do Diffraction and Reflection have in common?
Diffraction and reflection are both phenomena related to the interaction of waves with obstacles or surfaces. Diffraction involves the bending of waves around obstacles, while reflection involves the bouncing back of waves off a surface. Both processes illustrate how waves can be altered by encountering different mediums or boundaries in their path.
