Answer:
if it were to be digital then you would be able to carry it around where ever and look at it to remind you of the memories, however it probably wouldnt last as long as the physical one. eg if you phone breaks there is a chance to restore the photo but you would had to have backed it up beforehand.
Explanation:
Two waves with the same wavelength are in phase if there phase difference is zero or an integral multiple of wavelength. Thus the integer part of any difference expressed in wavelength can be discarded.
The phase difference of 5.4 wavelength is equivalent to is one of 0.4 wavelength thus the interference is an intermediate interference close to fully destructive.
in ideal gas we have few things that we need to follow as following
1. Force of interaction between gas molecules are negligible.
2. There is no effect of gravity on them
3. All collisions are perfectly elastic collision.
4. there will be no energy loss
5. All newton's law are valid for them.
6. all molecules moves with same speed in random direction.
So here in order to follow all above conditions we have to maintain low pressure and high temperature in the gas due to which the density of gas becomes low.
So correct answer will be
<em>The gas density is low and the temperature is high.</em>
