Use the drop-down menus to complete each sentence. Before starting the simulation and having the waves encounter the barrier, the wavelength is manipulated. This is the variable. The pattern of diffraction will vary as a result of the change in wavelength. The diffraction angle is therefore the variable. A “constant” is a parameter that stays the same regardless of the variables. The parameter of the barrier that is held constant is the .

Answer 1

Before starting the simulation and having the waves encounter the barrier, the wavelength is manipulated. This is the independent variable. The pattern of diffraction will vary as a result of the change in wavelength. The diffraction angle is therefore the dependent variable. A “constant” is a parameter that stays the same regardless of the variables. The parameter of the barrier that is held constant is the size.
