Test: Light & Shadow - 1 - Class 5 MCQ

When light from a source falls on an object, a part of it is bounced off, and this is called reflection of light.

A Lunar eclipse occurs when the Sun casts Earth's shadow onto the Moon. 

• When light falls on a transparent object, like a clear glass windowpane, almost all the light can pass through it.
• Transparent materials let light go through easily, so you can see clearly through them.
• It's like looking through a clean window.
• So, when light passes through a transparent object, all the light goes through it, making things visible on the other side.

A lunar eclipse occurs when the Earth is in between the sun and the moon, and its shadow falls on the moon, which occurs during a full moon phase

Light travels in a straight line, as thin beams of light called rays. This is known as rectilinear propagation of light.

• 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!

A solar eclipse occurs when the Moon comes between the Sun and the Earth, casting its shadow on Earth.

• 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.

• 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.
• 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.

• 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.
