When a beam of light is used to determine the position of an object, the maximum accuracy is achieved if the light is:
1 polarised
2 of longer wavelength
3 of shorter wavelength
4 of high intensity
Explanation:
: When a beam of light is used to determine the position of an object, the maximum accuracy is achieved, if the light is of shorter wavelength. Because if the wavelength is longer, the spread in the wave will be more.

How does the red shift confirm that the universe is expanding?
1 wavelength of light emitted by galaxies appears to decrease
2 wavelength of light emitted by galaxies appears to be the same
3 wavelength of light emitted by galaxies appears to increase
4 none of these
Explanation:
: According to Doppler's effect, if light source is moving away from the observer, then the wavelength of light emitted by the source appears to increase. The light received from galaxies shift towards the red end, i.e. toward longer wavelength. This means, the galaxies must be receding away, which leads to the conclusion that the universe is expanding.
