Solar and lunar eclipse

  1. 1. SOLAR LUNAR SUN SUN
  2. 2. ECLIPSES  The moon, the earth and other planets cast their own shadows in space.  Eclipses are examples of formation of shadows in space.  There are two types of eclipses – solar eclipse and lunar eclipse.  They are classified depending on the position of the sun, moon and the earth with relation to each other.
  3. 3. UMBRA AND PENUMBRA  If the source of light is wide two shadows can be seen. One shadow is completely dark called umbra, in the centre.  The other is a partial shadow called the penumbra , which surrounds the umbra.  The umbra doesn’t receive any light but the penumbra receives light from the source of light. penumbra umbra
  4. 4. SOLAR ECLIPSE  When the moon comes between the earth and the sun and when all three are in a straight line a solar eclipse is formed.  For the part which lies in the umbral region it is a total eclipse.  For the part which lies in the penumbral region it is a partial eclipse.  A solar eclipse occurs only on a new moon day. Did you know? The diamond ring effect observed during the total eclipse is said to be one of the most spectacular scenes ever to be witnessed.
  5. 5. LUNAR ECLIPSE  When the earth comes between the sun and the moon and all three are in the same straight line, the shadow of the earth falls on the moon and a lunar eclipse occurs.  A lunar eclipse occurs only on a full moon day.
