A laser-guided bomb is like a super-smart bomb that can be aimed very precisely at its target. Imagine you're playing a game of darts, but instead of throwing the dart at a board, you're throwing it at a specific spot on the ground. You want to hit that spot exactly, because if you miss, you might hit something else by accident.
The laser-guided bomb works in a similar way. First, a person (like a soldier or a pilot) uses a special device to shine a laser beam at the target they want to hit. The laser beam is like a tiny light that points right at the spot on the ground where they want the bomb to go.
Then, they launch the laser-guided bomb from an airplane or a helicopter. The bomb has special sensors on it that can "see" the laser beam shining on the ground. As it falls, the bomb uses those sensors to guide itself towards the laser beam – kind of like a "follow the leader" game.
When the bomb gets close to the target, it explodes and does what it's supposed to do – for example, it might destroy a building or a vehicle. Because the laser-guided bomb was so precise, it hit exactly where it was supposed to and didn't hurt anything else nearby.
In summary: a laser-guided bomb is a super-smart bomb that uses a laser beam to guide itself to a very specific target. It can go exactly where it's supposed to and avoid hurting anything else nearby.
