Transcribed Image Text:Astronomers observe a 66.0-MHz radio source both directly and by reflection from the sea as shown in the figure below. If the receiving dish is 17.0 m above sea level, what is the angle of the radio source above the horizon at first maximum?
**Diagram Explanation:**
The diagram includes:
1. **Direct Path**: A line indicating the direct path of the radio waves traveling in a straight line from the radio source to the radio telescope.
2. **Reflected Path**: A line indicating the path of the radio waves reflected from the surface of the sea before reaching the radio telescope.
3. **Radio Telescope**: A marker showing the location of the radio telescope positioned at 17.0 meters above sea level.
4. **Angle θ**: The angle between the direct path and the reflected path at the point of observation, which is to be determined.
The objective is to calculate the angle θ of the radio source above the horizon when the conditions for the first maximum are met.
