--->>>>>>>Unity 3d : I'm trying to make my program wait 0.1 seconds

Hi , I'm trying to make a jump script and I need to make the script wait 0.1 seconds between each statement
HERE

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class gravityControl : MonoBehaviour
6. {
7.  
8.     public bool isGrounded;
9.     Rigidbody rb;
10.     void Start(){
11.         rb = GetComponent<Rigidbody>();
12.     }
13.  
14.     void OnCollisionStay(){
15.         isGrounded = true;
16.      
17.     }
18.  
19.     void Update(){
20.         if(Input.GetKeyDown(KeyCode.Space) && isGrounded){
21.             transform.Translate(0f, 0.2f, 0f);
22.             //wait 0.1 seconds <----------------------------------
23.             transform.Translate(0f, 0.2f, 0f);
24.             //wait 0.1 seconds<----------------------------------
25.             transform.Translate(0f, 0.2f, 0f);
26.             //wait 0.1 seconds<----------------------------------
27.             transform.Translate(0f, 0.2f, 0f);
28.             //wait 0.1 seconds<----------------------------------
29.             transform.Translate(0f, 0.2f, 0f);
30.             //wait 0.1 seconds<----------------------------------
31.             transform.Translate(0f, 0.2f, 0f);
32.             //wait 0.1 seconds<----------------------------------
33.             transform.Translate(0f, 0.2f, 0f);
34.             //wait 0.1 seconds<----------------------------------
35.             transform.Translate(0f, 0.2f, 0f);
36.             //wait 0.1 seconds<----------------------------------
37.             transform.Translate(0f, 0.2f, 0f);
38.             //wait 0.1 seconds<----------------------------------
39.             transform.Translate(0f, 0.2f, 0f);
40.             isGrounded = false;
41.         }
42.     }
