How to scale perlin noise

[Pepsidog]

When creating perlin noise, I understand all but how to scale the amount of ‘waves’ on a noise texture. For example, how would I create

Multiply the inputs by some value. e.g. if you multiply by smaller numbers, you stretch the result (more like the top image).

More like the top image:

 Mathf.PerlinNoise(x * 0.25f, y * 0.25f);

More like the bottom image:

Mathf.PerlinNoise(x * 4f, y * 4f);
