What happens to diffraction pattern If red light is replaced by blue light?

When the red light is replaced by blue light, the wavelength decreases which means that the fringe width decreases and the pattern becomes narrower.

Does red or blue light diffract more?

In short, the angle of diffraction is directly proportional to the size of the wavelength. Hence red light (long wavelength) diffracts more than blue light (short wavelength).

How will the diffraction pattern changes when yellow light is replaced by blue light?

How will the diffraction pattern of single slit change when yellow light is replaced by blue light? The fringe will be. Since, wavelength of blue colour is less than yellow colour. Therefore, fringe will become narrower.

What does blue light undergo more than red light?

Blue light has shorter waves, with wavelengths between about 450 and 495 nanometers. Red light has longer waves, with wavelengths around 620 to 750 nm. Blue light has a higher frequency and carries more energy than red light.

What are the conditions for diffraction?

Answer : The phenomenon that occurs when the light comes across the object and it obstructs is known as diffraction. The essential condition for diffraction of light is given by, The wavelength of the light should always be comparable to the size of the object.

Which one of the following is most essential for observing diffraction of light?

As you have probably noticed, the diffraction pattern occurs only when the distance between the fingers is very small. It is the most essential condition for the diffraction to occur. The opening or slit width has to be comparable or less than the wavelength of light for prominent diffraction patterns.

Why does red diffract more than violet?

In the visible wavelengths of the electromagnetic spectrum, red, with the longest wavelength, is diffracted most; and violet, with the shortest wavelength, is diffracted least. Because each color is diffracted a different amount, each color bends at a different angle.

What is a diffraction pattern?

Diffraction-pattern meaning (physics) The pattern of lines or spots produced by diffraction; especially the two-dimensional pattern produced by X-ray diffraction that may be used to determine the structure of a crystal or of a crystalline compound.

What happens to diffraction if I monochromatic yellow light is replaced by red light II the distance between the source and the slit is halved?

Therefore, (i) the linear width will increase if the monochromatic yellow light is replaced with red light because red light has a larger wavelength than yellow. (ii) Similarly with the increase of distance between the screen and the slit the linear width of the central maximum will increase.

How will the diffraction pattern change?

The change in diffraction pattern of a single slit, when the monochromatic source of light is replaced by a source of white light will be. When a source of white light is used instead of a monochromatic source, the diffracted image of the slit gets dispersed into constituent colours of white light.

Which statement about red light and blue light is correct?

Statement (a) is correct. Since the . frequency of blue light is larger than red light, so the energy of blue light is also higher than the energy of red light.

Which Colour of light is responsible for greater rate of photosynthesis?

red light
The rate of photosynthesis is affected by the color of light that is absorbed the best by the chlorophyll pigment. Chlorophyll absorbs blue and red light energies with the greatest efficiency. The color that has the highest influence on photosynthesis is the blue color. The red light is next best for photosynthesis.
