Why do far away galaxies look red?
basically, according to the law of scattering light of longer wavelength scatters less hence, red light having the longest wavelength in the visible spectrum scatters less while all the other colors gets scattered
Why is there a red sunset?
A red sunset occurs when sunlight passes through a thicker layer of the Earth's atmosphere, scattering the shorter blue and green wavelengths. This leaves behind the longer red and orange wavelengths, creating the red hue we see in the sky.
Will the red or the violet end of the first-order spectrum be nearer the central maximum?
The red end of the first-order spectrum will be nearer the central maximum when using a diffraction grating because longer wavelengths bend less, causing red light to deviate less from its original path compared to violet light.
What is revealed by the red color of the supergiant star called Betelgeuse?
The red color of Betelgeuse indicates that it is a cooler star, emitting light at longer wavelengths in the red spectrum. This color indicates that Betelgeuse is a massive, aging star that is nearing the end of its life cycle.
What front causes precipitation to fall for longer periods of time but less intensely?
Does a cold front cause precipitation to fall for longer periods of time but less intensely
What wavelengths carry most energy?
Shorter wavelengths, such as gamma rays and X-rays, carry the most energy because they have high frequencies and short wavelengths, which is inversely proportional to their energy. Conversely, longer wavelengths like radio waves carry less energy because they have lower frequencies and longer wavelengths.
Are shorter wavelengths more affected by a prism or water droplets than longer wavelengths?
False. A prism separates the colors of sunlight into a spectrum because each wavelength of light has its own index of refraction, not because wavelengths are affected more or less by the prism.
Why are short wavelengths of EM radiation less common then medium wavelengths?
Shorter wavelengths, like gamma rays and X-rays, require more energy to produce than longer wavelengths like visual light.
Why do the waves with shorter wavelengths scatter more than those with long wavelength?
Waves with shorter wavelengths interact with smaller particles or obstacles in the medium, leading to more scattering. This is due to the wave's ability to couple more effectively with these smaller features. In contrast, longer waves interact less with these small particles, resulting in less scattering.
What is the relationship between the wavelength of microwaves and their ability to penetrate different materials?
The relationship between the wavelength of microwaves and their ability to penetrate different materials is that shorter wavelengths can penetrate materials more effectively than longer wavelengths. This is because shorter wavelengths have higher energy levels, allowing them to pass through materials with less resistance. Conversely, longer wavelengths are less able to penetrate materials due to their lower energy levels.
Why light with longer wavelength bend least?
Light with longer wavelengths bends least because their lower frequency results in less interaction with the medium through which they are passing. This lower interaction means less bending or diffraction occurs as the light waves pass through the medium. Shorter wavelengths, on the other hand, interact more with the medium, causing more bending.
Why wavelength gets longer the laser light can be focused to?
This is because longer wavelengths have lower energy and do not interact with matter as strongly. This means longer-wavelength light can be focused to a tighter spot because it is less prone to scattering or diffraction. Conversely, shorter wavelengths have higher energy and are more prone to scattering, leading to a wider focal spot.
What is the longest wavelength?
There is no longest wavelength. In the electromagnetic spectrum extremely low frequency waves can have wavelengths of less than 100 megametres (100,000 kilometres or 10^8 metres). Gravitational waves are likely to have much longer wavelengths.
Which type of light penetrates the least in water?
Red
What causes the sky to appear yellow?
The sky appears yellow when particles in the atmosphere scatter sunlight in a way that makes shorter blue and violet wavelengths less visible, leaving longer yellow and red wavelengths more prominent.
What color is least visible to the human eye and why?
The color least visible to the human eye is blue. This is because the human eye is less sensitive to shorter wavelengths of light, such as blue, compared to longer wavelengths like red and green.
Why do the colours in a spectrum split?
When light passes through a prism, it is refracted at different angles based on its wavelength. The longer wavelengths (red) are refracted less than the shorter wavelengths (violet), causing the colors to separate into a spectrum. This phenomenon is known as dispersion.
