A significant interaction suggests that the effect of one independent variable depends on the level of another independent variable. In this scenario, it is likely that there are different effects of each independent variable at different levels of the other independent variable. Therefore, at least one simple effect (i.e. the effect of one independent variable at a specific level of the other independent variable) is likely to be significant.
