What else can I help you with?
How does angular resolution change as observed wavelength gets longer?
For telescopes of the same size: if the wavelength gets longer, the maximum theoretical angular resolution gets larger (i.e., worse).
What happens to the frequency as the electromagnetic wave gets longer?
the frequency reduces in value. The longer the wavelength the lower the frequency.
Which color light has a longer wavelength?
The colour of visible light with the longest wavelength is red (approximately 700 nanometres).
Why do some galaxies look red when they should be white?
As the universe expands these galaxies are moving away from us. The light waves they give off appear stretched out which means they have a longer wavelength. Wavelength relates to the colour of light and the longer the wavelength the closer to red it looks.
Does red light have a longer wavelength then blue because it's the first colour in the rainbow?
Yes, red light has a longer wavelength than blue light. In the visible light spectrum, red light has a longer wavelength and lower frequency compared to blue light. This difference in wavelength is due to how light waves interact with various materials and how they are diffracted within the atmosphere.
As the wavelength of a wave increases on the electromagnetic spectrum what happens to the energy of the wave?
As a wavelength increases in size, its frequency and energy (E) decrease.
Do all colors have same wavelength?
No, because while the sun is rising the sun looks orange in colour because at that time the wavelength of orange colour rays will be more and while the sun is setting it looks in red colour because at that time the wavelength of red colour rays will be more. Normally the sky looks blue because at that time the wavelength of blue colour rays will be more.
Will a wavelength be shorter or longer the slower the object vibrates?
The wavelength will be longer if the object vibrates slower. Wavelength is inversely proportional to frequency; as frequency decreases, wavelength increases.
Does velocity of light increase or decrease by any colour?
The speed of light is a constant, doesn't change for colour. The wavelength changes by colour though. A white light source moving away real fast will become redder (longer waves), while the same source moving towards you will become bluer (shorter wavelength)
Which colour have longest wavelength in the visible spectrum?
Red light has the longest wavelength.
Which color has highest wavelength?
Red has the highest wavelength among the visible colors.
Is the slower an object vibrates the longer or shorter the wavelength will be?
The slower an object vibrates, the longer the wavelength will be. This is because wavelength is inversely related to frequency; as the frequency decreases (which occurs when the vibration slows), the wavelength increases. Therefore, a slower vibration results in a longer wavelength.
