level questions: scale bars and resolution
| Question | Answer |
|---|---|
| what would an increased magnification do to the resolution. | it will stay the same, it will not increase the resolution. |
| definitions of resolution | its the ability to distinguish between 2 seperate points |
| whats the difference between higher resolution and low resolution | if the 2 points are viewed as 2 seperate points its called resolved, if the 2 points are viewed as blurred together, its called not resolved |
| what should the light need to do? | hit a point to interfene with the light wave. |
| if the wavelength is 400nm (wavelength of light, used in light microscope), what is the smallest object you will be able to see | 200nm, half the wavelength of light |
| so what is the limit of wavelength | half of the wavelength of the light source we are using. we won't be able to resolve things smaller than 200nm |
| what does the electron microscope have over the light microscope | it has a higher resolution |
| what is different in the source of the electron microscope | we use a beam of electrons, so its not really based on the limit of wavelength, however its still has a wavelength, its just really tiny |
| what is the wavelength in the electron microscope. | only 1 nano metre |
| so what's the limit of wavelenght in an electron microscope | so we can see things down to 0.5 nano metres, we are going to see way more detail. |
| what would an increased magnification do to the resolution. | it will stay the same, it will not increase the resolution. |
