 ### Emissivity {#emissivity}
 
 The emissivity of materials highly depend on the surface finish (the more polished, the lower the emissivity).
-Some examples are given in <tab:emissivity_examples>.
+Some examples are given in [Table 1](#table--tab:emissivity-examples).
 
 Gold coating gives also a very low emissivity and is typically used in cryogenic applications.
