A tennis coach uses a speed gun to measure how fast the player serves the ball but some of the microwaves are absorbed by the tennis ball .what effect will these absorbed waves have on the ball?

The absorbed microwaves will cause the tennis ball to heat up slightly. This increase in temperature could potentially affect the elasticity and bounce of the ball, leading to a change in its performance during play. Additionally, the absorbed microwaves could also potentially cause damage to the ball over time if exposed to high levels of microwave radiation.
