00:00.000 --> 00:02.800
Today, we will understand the magic of light.

00:04.600 --> 00:08.400
On your way to a friend's house, you see many things around you.

00:08.700 --> 00:11.000
That's because the sun gives us light.

00:11.600 --> 00:13.600
Light helps us see objects.

00:13.800 --> 00:19.100
But when you walk into a dark room, you can't see anything because there's no light.

00:20.000 --> 00:24.200
But when someone turns on a light, now you can see everything again.

00:24.800 --> 00:28.300
But when light hits an object, it can't pass through it.

00:28.900 --> 00:31.100
That's when something interesting happens.

00:31.600 --> 00:33.100
A shadow appears.

00:33.800 --> 00:37.800
A shadow is the dark shape we see when an object blocks the light.

00:38.500 --> 00:44.900
You need a light source, such as the sun, a lamp, or a torch to create a shadow.

00:45.400 --> 00:46.300
And guess what?

00:46.800 --> 00:51.400
Both living things and non-living things can make shadows.

00:52.500 --> 00:56.400
Sometimes light bounces back, like when it hits a mirror.

00:56.900 --> 00:58.500
That's called reflection.

00:59.000 --> 01:02.100
The light changes direction and comes back to our eyes.

01:02.600 --> 01:04.900
That's why we can see ourselves in the mirror.

01:06.900 --> 01:11.400
And other times, light goes through clear things like glass or clean water.

01:11.700 --> 01:13.100
That's called transparency.

01:13.500 --> 01:16.800
The light passes through so we can still see what's on the other side,

01:17.100 --> 01:18.600
like looking out of a window.

01:19.900 --> 01:20.800
See the difference?

01:21.100 --> 01:23.500
One apple looks real with light and shadow.

01:24.000 --> 01:25.200
The other looks flat.

01:25.500 --> 01:26.300
No light.

01:26.400 --> 01:27.400
No shine.

01:28.000 --> 01:29.700
That's the power of light.

01:30.100 --> 01:31.300
Thank you, light.
