What happens to an electromagnetic wave's frequency as it's wavelength decreases?
The product of (wavelength) x (frequency) of any wave phenomenon is alwaysthe same number ... the speed of the wave. So if wavelength changes, thenfrequency must change by exactly the same factor in the opposite direction,in order for their product to remain constant.
When matter absorbs a photon what is the relationship between the energy of the matter before and after the absorpion and the frequency and the wavelength of the radiation absorbed?
After the absorption, the matter has added energy equal to 'hf' the energy of the absorbed photon.
Do waves with a shorter wavelengths travel faster than waves with longer wavelengths?
The physical length, short wavelengths are shorter than long wavelengthsThe frequency, short wavelengths are higher frequency than long wavelengthsThe energy per photon, short wavelengths have more energy per photon than long wavelengths
How far in nanometers is the wavelength of a 10000 Hz sine wave and how far for a 20000 Hz sine wave also?
Wavelength = (speed)/(frequency)For a 10,000 Hz wave:,Wavelength = (speed)/(10,000) metersThat's (speed) x 100,000 nanometers.,For a 20,000 Hz wave:,Having doubled the frequency, the wavelength has now been reduced by half.So wavelength is now (speed) x 50,000 nanometers.,Note: It's often nice to be able to work with sine waves, but when you're only talking about frequency and wavelength, the wave-shape doesn't matter.
What did you observe with the product of wavelength and frequency for each color?
Well, I wasn't actually there, so I didn't observe anything. But from my education and personal experience, I know that the product of the wavelength and frequency of any wave is the wave's speed. So I should expect that the product of wavelength and frequency for any color of light, and for that matter, any electromagnetic wave, is always the same number, and ought to always be very close to the speed of light in the medium in which you observed it, or would have observed it had you been there.
What does increasing the frequency of X or Gamma ray do to its wavelength?
Increasing the frequency of any electromagnetic wave ... or of any wave for that matter ... decreases its wavelength.
Why won't a very bright beam of red light impart more energy to an electron than a feeble beam of violet light?
Ok, so this goes back to the inverse relationship between wavelength and frequency ( energy). As wavelength increases , frequency decreases, the relationship between the two is a inverse relationship. the Red light, wavelength of approx. 700 m^-7 , has a greater wavelength then of the blue light, 400m ^-7. This means , due to frequency and wavelength having an inverse relationship, blue light has a greater frequency (energy) than red light. This is why blue light, no matter how dim, will impart more energy to an electron , then a red light would.

How do wavelength and frequency relate to the speed of light?
c=lamda*f c is a constant, which is the speed of light, lamda is the wavelength which the light is traveling at, and f is the frequency of the light. All light travels at the speed of light no matter what colour, however ever colour tavels at different wavelengths and frequencies.

What is a electron micrscope?
Instead light electron beam is used. Wave nature of matter is being used in this device. Resolving power depends inversely on the wavelength of the light or radiation being used. So to improve the resolving power some 2000 times we have to use electron beam whose de Broglie wavelength is of the order 10-10 m
Why do light rays bend twice in lenss?
light is both atom and wave,in this task we will take light as a wave.all waves have speed,wavelength and frequency. When light gets into the lense wavelength diminishes so the speed diminish. when it comes back to air wavelength augments so the speed augments.this makes the illusion that a light ray bend in lenses. keep in mind that frequency never changes and the wavelength depends on the state of matter that the light is.
Do xrays and gamma rays have higher frequencies than ultraviolet rays?
Because that term is the name we have given to electromagnetic radiation with the highest observed frequency. If they had lower frequency, then we would call them by another name. And if they're called by that name, then they must be rays of the highest observed frequency, all because that is how we have defined them.
3 A wave with which of the following frequencies would have the shortest wavelength?
So far in the electromagnetic spectrum we have gamma radiations having the shortest wavelength. In case of de Broglie's waves the matter waves of massive objects such as an iron ball moving at a faster rate would have the shortest wavelength which could not be measured even. So we declare that only light particles such as electron, proton, neutron or alpha particle, deutron moving at higher speeds would act as a wave with shortest wavelength.
