When we shine a laser through a glass of water with few drops of milk, we can see the path of light. This effect is often called the Tyndall effect.  Mahesh Shenoy video https://cdn.kastatic.org/googleusercontent/u58_VbsEYsBGIc6NKV0EcOpyFTvqmlK_0Bcc5izrVlBgCDiRLqSLBuzFqIz0TfYSx_9VGhUinbnm0sIxTQyvM-KD Scattering of light & Tyndall effect Let's explore the scattering of light with the help of an experiment.

For those inside the shadow, the sun's disk is fully blocked from view. Solar eclipses can occur only during a new moon, when the moon and the sun are on the same side of Earth.

When the shadow fully covers the moon, the eclipse is total. When the shadow partially covers the moon, the eclipse is partial. Lunar eclipses can occur only during a full moon, when the moon and the sun are on opposite sides of Earth.
