2D How to reflect a raycast with a line renderer

hi, I'm a beginner (sorry for my bad english), I've been looking for few hours to find a way to reflect a Raycast for a laser that reflects on certain surfaces. , I think I need vector2.reflect or something like that, but i don't really undertsand how it work ^^' , so does there is someone who can explain it to me? For now i have this alt text

 private LineRenderer lineRenderer;
 public Transform LaserHit;
 public bool isActive = true;
 
 
 
 void Start()
 {
     
     
     lineRenderer = GetComponent<LineRenderer>();
     lineRenderer.enabled = true;
     lineRenderer.useWorldSpace = true;
 
 }
 void Update()
 {
 
 
     if (isActive)
     {
 
         RaycastHit2D hit = Physics2D.Raycast(transform.position, transform.up);
 
         if (hit && hit.transform.tag == "Player" && isActive)
         {
             
             PlayerHealth playerHealth = hit.transform.GetComponent<PlayerHealth>();
             playerHealth.TakeDamage(10);
 
           
 
             StartCoroutine(laserHitWaitTime());
         }
         else if (hit.transform.tag == ("PF") )
         {
             // here the reflection effect
            
         }
         Debug.DrawLine(transform.position, hit.point);
         LaserHit.position = hit.point;
         lineRenderer.SetPosition(0, transform.position);
         lineRenderer.SetPosition(1, LaserHit.position);
 
     }
 
 
 }
 
 private IEnumerator laserHitWaitTime()
 {
 
     yield return new WaitForSeconds(0.3f);
     lineRenderer.enabled = false;
     lineRenderer.useWorldSpace = false;
     
     isActive = false;
 
     yield return new WaitForSeconds(3);
    
     isActive = true;
     lineRenderer.enabled = true;
     lineRenderer.useWorldSpace = true;
 }
