I'd be very happy if you'd answer this, and I'm looking more for the effect of gravity on time, rather than speed.

Wouldn't Bob still receive the light at one oscillation per second?If Alice claims she sends light with frequency 1, that is one oscillation per second then Bob will receive less then one oscillation per second.
Gravity affects time by causing a phenomenon known as time dilation, which is the slowing down of time in the presence of a strong gravitational field. This means that time will appear to pass slower in a stronger gravitational field compared to a weaker one.
Time dilation is caused by the warping of space-time by massive objects like planets, stars, and black holes. This warping of space-time is a result of the strong gravitational force exerted by these objects.
Time dilation can be measured using atomic clocks, which are very precise timekeeping devices. By comparing the time on a clock placed in a strong gravitational field with the time on a clock placed in a weak gravitational field, scientists can measure the difference in time and determine the amount of time dilation.
Yes, time dilation is noticeable on Earth, but the effect is very small due to the relatively weak gravitational field of our planet. However, it has been observed and measured using highly precise atomic clocks on airplanes and satellites.
Yes, time dilation has practical applications in fields such as GPS navigation and space travel. GPS satellites, which are in orbit around the Earth, experience time dilation due to their high speed and distance from Earth's surface. This must be taken into account when calculating accurate GPS coordinates. Time dilation also plays a crucial role in the accuracy of space travel and communication between spacecrafts.
