Chapter 488 Physics Lab


    It was the weekend. Xander rode his bike to Lewis Manor. When he saw Harold, he greeted him


    politely. "Mr. Lewis Senior!"

    Harold looked delighted to see Xander. "Xander, have youe to see Caleb and Victor? The two


    of them aren''t home today. They left early this morning."


    "It''s okay, Mr. Lewis Senior. I''m not here to see them! I''m here for Gracie."


    Harold smiled knowingly. "I see! Then, I''ll get the housekeeper to call her downstairs."


    He called the housekeeper and said, "Go and tell Gracie that Xander is here. Tell her to hurry up


    ande downstairs."


    "It''s okay, Mr. Lewis Senior. I''ll wait for her here." Xander had just finished speaking when he heard


    the thumping of footsteps on the stairs.


    Soon, Grace ran into the living room. "Xander, you''re here!"


    Xander murmured in assent and looked at Harold. "We''ll get going now, Mr. Lewis Senior."


    Harold nodded. "Okay, off you go!"


    The moment they went out, Grace was filled with questions. "Xander, where are you taking me?


    Why are you being so mysterious?"


    But Xander kept his lips sealed. "I''m not going to tell you yet. You''ll know in a moment when we get


    there."


    Grace murmured in assent. "Okay."


    Xander got on his bicycle and extended a sincere invitation. "Get on!"


    Grace didn''t hesitate and sat on the back of the bicycle. When he saw that she was seated, Xander


    stepped on the pedals and slowly rode off.


    …


    When they reached their destination, Grace was confused. "What is this ce, Xander?"


    Xander grabbed her arm. "Come on, let''s go in and see!"


    The two of them entered, and they saw that the room was filled with all sorts of equipment used in


    physics experiments.


    Some of the equipment looked very strange, and it caught Grace''s interest immediately.


    "Xander, what is this?"


    "That''s a concave-convex lens."


    "It looks so strange! What about this, then?"


    "That''s a resistance box, and beside it are an ohmmeter and an ammeter."


    Grace was awed into silence. After entering the physicsb, she was filled with curiosity about


    everything.


    Xander patiently answered all her questions until the two of them walked to the other side of theb.


    Only then did he stop and look at her. "Do you want to try doing a physics experiment?"


    Grace asked in hesitation, "Me?"


    "Yep. Do you want to try?"


    Grace was reluctant to do it. "No, I don''t know how to do it."


    "It''s okay. Try it. You''ll definitely be able to do it."


    Under Xander''s patient encouragement, Grace finally agreed. Xander guided her through an


    experiment with a pinhole camera, step by step.


    When the experiment had ended, Grace looked at her experiment results in awe. She couldn''t help


    crying out, "It''s upside down and flipped from left to right! What is going on?"


    Xander patiently exined, "A pinhole camera is based on the principle of light being in a constant


    medium, and when it''s not affected by gravity, it will transmit in a straight line. This is the rectilinear


    propagation of light …"


    After listening to Xander''s exnation, Grace thought that it was quite interesting. "Xander, let''s do


    some other experiments."


    Xander saw that her interest had been piqued, and without a moment''s hesitation, he went through


    all the physics experiments for the school year with her.


    The two of them stayed in theb from morning to night, until Xander finally lifted his wrist to look at


    the time. "It''s gettingte, Gracie. We should go back."


    Grace was reluctant to leave. "No, this experiment isn''t done yet. Let''s wait for the result before


    leaving."
