Waves

When a waves goes from 1 medium to another, the frequency stays the same but the wavelength and wave speed changes.
Can somebody please draw a wave where the wavelength has increased without the frequency having changed.

I don't really understand the concept of frequency staying the same as a wave travels through a different medium.
If the frequency changes it's not the same wave anymore. It's always the wavelength and the speed changing due to change in the refractive index between the two mediums

Would you be able to draw it and show?
