During a solar eclipse, Baily's Beads are formed when the rugged terrain of the Moon allows sunlight to shine through in some places, creating bright patches that can be seen just before totality. True or False?

True. Baily's Beads appear when the uneven mountains and valleys on the Moon’s edge let sunlight slip through in a few small spots. As the Moon’s shadow moves over the Sun, the light shines through the lunar valleys and creates bright “beads” just before the Sun is completely covered. The effect happens only at the instant the Sun’s disk is about to disappear, so it is seen right before totality. For example, when a valley on the Moon’s limb opens a tiny window, a single bright bead can be seen for a few seconds before the Sun vanishes.
