Why does light of shorter wavelength produce a clearer image than light of longer wavelengths?
One of the basic consequences of the wave theory of light is:
a wave can react only with an object that has a dimension that is equal to or greater than the wavelength of the wave.
This was one of the most impressive demonstrations that I can remember from my education and it was done in grade eight with nothing more complex than a ripple tank.
Therefore in order to see molecules you have to use light (or electron waves) at or above the frequency of x-rays or gamma rays. Radar can do no better than displaying a blimp of quite massive objects.
What else can I help you with?
Does red or violet have the shortest wavelength?
Violet light has a shorter wavelength than red light. In the visible light spectrum, colors with shorter wavelengths, like violet, are located at the higher end of the spectrum, while colors with longer wavelengths, like red, are at the lower end.
Why x-ray have preferred a shorter shovel?
X-rays have shorter wavelengths that are better suited to interacting with smaller atomic structures and providing detailed images of tissues and bones. A shorter wavelength allows for higher resolution and clearer images, making them ideal for medical imaging applications.
Explain the relationship between the resolving power of the microscope and the wavelength of the light being used?
The resolving power of a microscope is inversely proportional to the wavelength of light being used. This means that as the wavelength of light decreases, the resolving power of the microscope increases. Shorter wavelengths can resolve smaller details, allowing for higher magnification and clearer images.
What wavelengths are shorter than 380 NM?
Any whose wavelength does not exceed 379 nm.
Is it true ultraviolet light had longer wavelength than visible light?
No, ultraviolet light has a shorter wavelength than visible light. Visible light falls within the electromagnetic spectrum with wavelengths ranging from approximately 400 to 700 nanometers, while ultraviolet light has shorter wavelengths below 400 nanometers.
Why does changing the wavelength change the sound?
Changing the wavelength of a sound wave changes the pitch of the sound. Shorter wavelengths produce higher pitch sounds, while longer wavelengths produce lower pitch sounds. This is because the frequency of the sound wave (which determines pitch) is inversely proportional to the wavelength.
Is the wavelength of x-rays longer or shorter then the wavelengths of visible light?
"shorter"
Do waves with the shortest wavelength have the slowest frequencies?
No, waves with shorter wavelengths have higher frequencies. The wavelength is inversely proportional to frequency, meaning shorter wavelengths correspond to higher frequencies.
How does interference pattern change when wavelength of light is used?
Shorter wavelengths produce interference patterns with narrower fringes and greater separation between them, while longer wavelengths produce interference patterns with wider fringes and smaller separation between them. The spacing of fringes is proportional to the wavelength of light.
Does red or violet have the shortest wavelength?
Violet light has a shorter wavelength than red light. In the visible light spectrum, colors with shorter wavelengths, like violet, are located at the higher end of the spectrum, while colors with longer wavelengths, like red, are at the lower end.
How does wavelength affect of sound?
Wavelength affects the pitch of sound: shorter wavelengths correspond to higher pitch, and longer wavelengths correspond to lower pitch. In the context of sound waves, shorter wavelengths are associated with higher frequencies, while longer wavelengths are associated with lower frequencies.
The color of light is determined by its?
Wavelength, or alternatively its frequency.
What travels faster short or long wavelength?
Short wavelengths travel faster than long wavelengths. This is because light travels at a constant speed, and since wavelength is inversely related to frequency (shorter wavelength means higher frequency), shorter wavelengths have higher frequencies and thus travel faster.
When they say Increasing wavelength Referring to spectrum do they mean short wavelengths?
increasing wavelength means shorter frequency.
Are green wavelengths longer than orange wavelengths?
No, green wavelengths are shorter than orange wavelengths. In the electromagnetic spectrum, longer wavelengths correspond to colors such as red and orange, while shorter wavelengths correspond to colors like blue and green.
What waves have shorter wavelength's than microwaves?
X-rays and gamma rays have shorter wavelengths than microwaves.
What covers the light of a microscope to shorten the wavelength?
A blue filter only allows shorter wavelengths of light to pass. So, covering the light source of a light microscope with a blue filter shortens the wavelength of light passing through the objective.
