Test: Light & Shadow - 1 - Question 7

State whether the following statement is True or False:

Light is made up of three colours.

Detailed Solution for Test: Light & Shadow - 1 - Question 7
  • Actually, light is made up of seven colours, not three.
  • When sunlight passes through raindrops, it separates into seven colours - violet, indigo, blue, green, yellow, orange, and red, forming a rainbow.
  • So, the statement that light is made up of three colours is not true.
  • Remember, these colours make up the word VIBGYOR when you take their first letters.
  • So, light is a combination of these seven beautiful colours!

What type of material allows only some light to pass through but not enough to see clearly through them?
Detailed Solution for Test: Light & Shadow - 1 - Question 8
  • Translucent materials are like a kind of see-through wrapping paper. They allow some light to go through, but not enough for you to see things clearly.
  • Imagine a frosted glass where light can pass through, but you can't see clearly through it. That's what translucent means - letting some light through but not all.
Test: Light & Shadow - 1 - Question 9

What happens when light from an electric bulb falls on a book?

Detailed Solution for Test: Light & Shadow - 1 - Question 9
  1. When light from an electric bulb falls on a book, a part of it bounces off. This bouncing off of light by objects is called reflection of light. It's like how when you throw a ball against a wall, it bounces back to you.
  2. Light does the same thing when it hits objects like books or walls, bouncing off and reaching our eyes so we can see things around us.
Test: Light & Shadow - 1 - Question 10

State whether the following statement is True or False:

A shadow always forms on the same side as the source of light.

Detailed Solution for Test: Light & Shadow - 1 - Question 10
  • When an object blocks light, a shadow forms on the opposite side of the object to where the light is coming from.
  • This means if the light is coming from the left, the shadow will form on the right side of the object.
  • So, the statement that a shadow always forms on the same side as the source of light is False.
