they are two conditions
1. the incident ray , refracted ray and the normal all lie in the same plane. The refracted ray ant the incident ray are on opposite sides of the line that separates the two medium.
2. Light bends toward the normal when the speed of light in the second medium is less than the speed of light in the first medium. Light bends away from the normal when the speed of light in the second medium is greater.

How can diffraction occur in water?
Diffraction can occur in water when water waves encounter an obstacle or pass through a narrow opening, causing the waves to bend and spread out. This bending and spreading of the waves is known as diffraction, and it is a common phenomenon in water due to the wave nature of water molecules.
What should be approximate size of slit to observe diffraction?
The width of the slit should be on the order of the wavelength of the light being used for diffraction in order to observe the diffraction pattern clearly. This is known as the single-slit diffraction condition. The size of the slit also affects the angular spread of the diffraction pattern.
What are Conditions of diffraction?
Conditions of diffraction refer to the requirements that must be met in order for diffraction to occur, such as having a wave encounter an obstacle or aperture that is comparable in size to the wavelength of the wave. Additionally, the wave must be coherent and the path difference between different parts of the wave should be within half a wavelength to observe constructive interference.
Does diffraction become more or less pronounced for bigger openings?
Diffraction becomes less pronounced for bigger openings. This is because diffraction can only occur when the size of the opening is comparable to the wavelength of the wave. When the opening is larger, the diffraction effects become less significant.
When does the greatest amount f diffraction occur?
The greatest amount of diffraction occurs when the size of the opening or obstacle is comparable to the wavelength of the wave. This is known as the principle of diffraction, where larger obstructions cause greater bending of the waves around them.
What is the angle, in degrees, of the first diffraction order?
The angle of the first diffraction order is typically around 30 degrees.

If heat is required for a reaction to occur what type of reaction is it?
If heat is required for a reaction to occur, it is an endothermic reaction. Endothermic reactions absorb heat from their surroundings in order to proceed.
Which will not occur when a light ray interacts with a smooth pane of class?
Diffraction will not occur when a light ray interacts with a smooth pane of glass. Diffraction is a phenomenon where light bends around obstacles or spreads out after passing through a narrow opening, but on a smooth pane of glass, the light will either be transmitted or reflected without undergoing diffraction.
When does most diffraction occur in a wave?
Most diffraction occurs when the size of the obstacle or aperture is comparable to the wavelength of the wave. This is because diffraction is the bending of waves around obstacles or through openings, and the extent of bending is influenced by the size of the obstacle or aperture.
Why does diffraction not occur when light passes through a window?
Diffraction does occur when light passes through a window, but the effect is typically minimal due to the small size of the window relative to the wavelength of light. The amount of diffraction is directly proportional to the size of the obstacle or aperture; since windows are relatively small compared to the wavelength of visible light, the diffraction effects are not easily observable.
What is the condition for absent spectra in a diffraction grating?
In a plane diffraction grating, if the angle of diffraction is such that the minima due to diffraction component in the intensity distribution falls at the same positions of principal maxima due to interference component, then, that order of principal maxima will be missing or absent.

What is the relationship between the diffraction angle and the wavelength of light in a diffraction grating experiment?
In a diffraction grating experiment, the relationship between the diffraction angle and the wavelength of light is described by the equation: d(sin) m. Here, d is the spacing between the slits on the grating, is the diffraction angle, m is the order of the diffraction peak, and is the wavelength of light. This equation shows that the diffraction angle is directly related to the wavelength of light, with a smaller wavelength resulting in a larger diffraction angle.
