FAQs on Class 5 Science - Light and Shadow - CBSE Worksheets - 1

1. What is light, and why is it important for us?
Ans.Light is a form of energy that allows us to see the world around us. It is important because it helps plants grow through photosynthesis, provides warmth, and enables us to perform daily activities by illuminating our surroundings.
2. How do shadows form?
Ans.Shadows are formed when an opaque object blocks the path of light. When light from a source, like the sun or a lamp, hits an object, it cannot pass through, creating a dark area behind the object where the light is obstructed.
3. What are the different types of shadows?
Ans.There are two main types of shadows: a umbra and a penumbra. The umbra is the darkest part of the shadow where the light is completely blocked, while the penumbra is the lighter part surrounding the umbra, where some light still reaches.
4. How do we use light and shadow in our daily lives?
Ans.We use light and shadow in various ways, such as determining the time of day by observing shadows, creating art and photography, and using shadows to enhance storytelling and visuals in theater and film.
5. How can we make our own shadows at home?
Ans.To make your own shadows at home, you can use a light source, like a flashlight or a lamp, and place an opaque object, such as your hand or a toy, in front of it. Adjust the distance between the light and the object to see how the size and shape of the shadow change.
