In this video we define the Greek letter λ (lambda) as it applies to electrical engineering. λ refers to the wavelength of a given electromagnetic wave. It can be found by dividing C, the speed of light, by f, the frequency of the wave.

Single Color Lithophane Printing Made Easy! (3D Printed Picture)
In this video we look at taking a photograph and converting it into a lithophane. (*From Wikipedia - A lithophane is a thin plaque of translucent material, normally porcelain, which has been moulded to varying thickness, such that when lit from behind the different thicknesses show as different shades, forming an image. Only when lit from behind does the image display properly.[2] They were invented in the 19th century and became very popular, typically for lampshades, nightlights, or to be hung on windows. They could also be given stands, to be placed in front of a light source.).
I did the printing on my Qidi Tech X Plus 3, but any 3D printer works for this.
The website that does the photo to .stl conversion is: https://3dp.rocks/lithophane/
