Is the scene being drawn correctly with my raytracer?

Question

I have a ray tracer that I wrote myself.

I am not sure that the scene is being drawn correctly, to be more precise, are my reflections on the floor and on the sphere correct?

My scene:

s = Scene(
        [
            Light(
                type_=LightType.ambient, 
                intensity=vec3(0.2, 0.2, 0.2)
            ),
            Light(
                type_=LightType.directional,
                intensity=vec3(0.5, 0.5, 0.5), 
                direction=vec3(0, -2, -1)
            ),
        ],
        [
            Triangle(vec3(-1, -1, 2), vec3(1, -1, 2), vec3(-1, -1, 5), color=vec3(255, 255, 255), specular=500, reflective=0.5),
            Triangle(vec3(1, -1, 2), vec3(1, -1, 5), vec3(-1, -1, 5), color=vec3(255, 255, 255), specular=500, reflective=0.5),
            Triangle(vec3(-1, 1, 5), vec3(-1, -1, 5), vec3(1, -1, 5), color=vec3(0, 255, 255), specular=500, reflective=0),
            Triangle(vec3(-1, 1, 5), vec3(1, -1, 5), vec3(1, 1, 5), color=vec3(0, 255, 255), specular=500, reflective=0),
            
            Sphere(
                color=u8vec3(200, 200, 200), 
                radius=0.5, 
                center=vec3(0, 0, 4),
                specular=-1,
                reflective = 0.8
            )
        ]
)

Result:

And yes, sorry in advance, I'm a beginner)
