Light in space travels through _________.

Solution for the question - light in space travels through _________. vacuumglassflaskpressure

Light in space travels through _________.-Turito

<ul>
<li>In the absence of light we cannot see anything in the room.</li>
<li>When light falls on any object, it is reflected from the said object and enters our eye.</li>
<li>Light stimulates the photoreceptors present in the eye and the image falls on the retina.</li>
<li>From the retina brains for the signal and interpret the object and tell us what we have seen.</li>
<li>Thus, without light no photoreceptors would stimulate and an image is formed on the retina.</li>
<li>Therefore, light is important for vision.</li>
</ul>
