Shadertoy: The sin math function - 002.

This is another shader example to draw a sine math function using a sine wave, see Wikipedia. I used shadertoy website and the mat sin function by time. The source code is commented for a better understanding of it.

// this size of line to paint each pixel from screen
const float size = 0.01;

void mainImage( out vec4 fragColor, in vec2 fragCoord )
{
    // Normalized pixel coordinates (from 0 to 1)
    vec2 uv = fragCoord/iResolution.xy;
    // resize uv 
    uv = uv  * 2.0;
    // translate normalized pixel coordinates uv from [0,1] to [-1, 1] with 
    uv = (uv - 1.0);

    // get uv.x aspect ratio
    uv.x *= iResolution.x / iResolution.y;
  
    // get simple sine 
    //float t = sin(uv.x);

    // get sine * 3 with same size uv will zoom the sine graphic
    // see also https://en.wikipedia.org/wiki/Sine_wave
    float t = sin(uv.x * 3.0);
    
 // select domain area of sine and drwa yellow color 
    // else put an blue color on rest
    if (uv.y >= t - size && uv.y <= t + size) {
        // draw sine
     fragColor = vec4(1.0,1.0,0.0,1.0);
    } else {
        // draw background
        fragColor = vec4(0.0,0.0,1.0,1.0);
    }
}

The result of this shader is this:

Shadertoy: The flag of Romania - 002.

This is another step about learning shaders.
The old example can be updated with this source code.
I commented on the source code to see step by step how this working.
One way to understand how this working to the final result is to going back on the shader structures that generate output to the basic elements of the shader.
If we apply this case to solve the problem then from the display a color like a vec4 color for fragColor adding a sin function to wave the result, and so on.
Right, this code can be optimized in many ways depending on the result.

// learning process area step by step 
// the gl_FragColor is a vec4 type of float values in the range 0 to 1.
// because the values are from 0 to 1  this can used in many ways with for domain and range
void mainImage( out vec4 fragColor, in vec2 fragCoord )
{
    // Normalized pixel coordinates (from 0 to 1)
    vec2 uv = fragCoord/iResolution.xy;
    // define a vec2 and uv can be divide to create waves 
    // use this to see the difference 
    // vec2 valul = vec2(0.01,1.0);
    vec2 valul = vec2(0.5,1.0);
    // define a vec2 this vector will be the vector of shadow
    vec2 unghi_valul = vec2(0.5,1.0);
    // this float will speed the animation with iTime
    float viteza = 3.0;
    // with the dot we can calculate the dot product of two vectors and result can be a shadow
    // the result of unghi can be changed when change the vectors and vectors math rules
    float unghi = dot(uv/valul, unghi_valul) - iTime * viteza;
    // the output can be used with sin to create a shadow wave
    // fill the screen with red
    fragColor = vec4(1,0,0,0) * sin(unghi);
    // fill the 2/3 of size with yellow color
    if(uv.x<(1.0/1.5))
    fragColor = vec4(1,1,0,0)  * sin(unghi);
    // fill the last 1/3 with the blue color 
    if(uv.x<1.0/3.0)
    fragColor = vec4(0,0,1,0)  * sin(unghi);
}

The result of this source code:
