Step-by-step explanation:
The relation between angular frequency and frequency is directly proportional:
![\omega=2\pi f](https://img.qammunity.org/2020/formulas/physics/college/juoymztubsza7fdx9hdten7ix6liiv8ylo.png)
So, if the angular frequency decreases, the frequency also decreases.
The relation between angular frequency and period is inversely proportional:
![\omega=(2\pi)/(T)](https://img.qammunity.org/2020/formulas/geography/high-school/2bvenhnyw6np3ujzywcg1o9i3kotocqdh6.png)
So, if the angular frequency decreases, the period increases.
