How can I delay my explosion script?

Hello, I am a beginner scripter. I've just made my first script involving a landmine. Touching the landmine will of course explode upon contact. The problem here is that it doesn't have a delay. Every part it touches will explode immediately. I just wanted to explode at least every second. Here's the code:

function ExplodePart(part)
	local explosion = Instance.new("Explosion")
	explosion.BlastRadius = 10
	explosion.Position = part.Position
	explosion.Parent = game.Workspace
end


landMine = game.Workspace.Landmine

landMine.Touched:connect(ExplodePart)

Please help a beginner scripter out. ;)

EDIT: Sorry for the mistake but what I mean is that it need to explode and DELAY after it. Multiple explosions happen at once!

Use wait()

function ExplodePart(part)
wait(1) -- in the parentheses, type the number of seconds you want the script to wait
    local explosion = Instance.new("Explosion")
    explosion.BlastRadius = 10
    explosion.Position = part.Position
    explosion.Parent = game.Workspace
end


landMine = game.Workspace.Landmine

landMine.Touched:connect(ExplodePart)

do you want multiple explosions when you touch the landmine? i don't really know what you're trying to say. but here's my script:

AmountOfExplosions = 5 -- here is how much explosions you want
landMine = game.Workspace.Landmine

function ExplodePart(part)
	for i = 1, AmountOfExplosions do
    	local explosion = Instance.new("Explosion")
    	explosion.BlastRadius = 10
    	explosion.Position = part.Position
    	explosion.Parent = game.Workspace
		wait(1) -- how long to wait between each explosion
	end
end


landMine.Touched:connect(ExplodePart)
