Can you transition smoothly between 2 numerical values without increments?

so i know you can increase a numerical value using small increments but is there any way to do it fully smoothly

so something like this but instead of the wait at "HERE" then something to smoothly transition between the values

part = game.Workspace.Part
touchpad = script.Parent

cd = false

touchpad.Touched:Connect(function(p)
if p.Parent:FindFirstChild("HumanoidRootPart") then
    if cd == false then
        cd = true
        part.Transparency = 1
        wait(1) -- HERE
        part.Transparency = 0
        cd = false
    end
end
