Question

Explain the construction and working of optical telescope ​ ( 5 mark question )​

Answer 1

$\huge\red{\underline\orange{\underline\purple{Answer:}}}$Refracting telescopes work by using two lenses to focus the light and make it look like the object is closer to you than it really is. Both lenses are in a shape that's called 'convex'. Convex lenses work by bending light inwards (like in the diagram). This is what makes the image look smaller.
