The slope going straight up the hill is greater than the slope of winding around. You drive more distance to decrease the pull of gravity.
When frequency increases, the diffraction of a wave becomes less pronounced. Higher frequencies have shorter wavelengths, making it easier for the wave to travel in a straight line and less likely to diffract around obstacles.
Yes, they do. But they sometimes travel a straight line through bent space.
All electromagnetic radiation from VHF and higher frequencies (including visible light) travels only in straight lines. However these frequencies will reflect off certain surfaces, one surface that visible light reflects off is a mirror, which if properly arranged can be used to see around corners.
Light travels in a straight line, moving in a straight path known as a ray.
The phenomenon where light waves travel in straight lines is called rectilinear propagation. This means that light travels in a straight path unless it encounters a medium that causes it to change direction.
They built straight roads so that they could travel quicker; thus covering less territory.
A pass in a mountain range is commonly referred to as a mountain pass. It is a route through a mountain range or over a ridge that allows for easier travel between two regions separated by mountains.
they are invented so people can travel around easier
The term for the natural gap in a mountain ridge is called a "pass" or a "col." These are low points that allow for easier travel between two adjacent valleys or mountain peaks.
If you followed a straight line around the equator you would travel 40,075 Km (24,902 miles) to return to your starting point.
When frequency increases, the diffraction of a wave becomes less pronounced. Higher frequencies have shorter wavelengths, making it easier for the wave to travel in a straight line and less likely to diffract around obstacles.
The low point of a mountain range is called a pass. In contrast, the high point is called a peak.
Travel easier
Signals in the VHF frequencies have a tendency to follow the curve of the earth and bend around hills where UHF tends to travel more in a straight line.
Mountain Designs sell innovative outdoor and travel goods to adventure seekers around the world. Their quality products deliver the ultimate functionality.
A system of well-maintained mountain passes or a network of tunnels would allow easier travel between Afghanistan and Pakistan through the mountains. Additionally, the construction of roads and bridges would also facilitate travel in this rugged terrain.
The moon doesn't actually travel in a straight line; it orbits around the Earth in an elliptical path due to the gravitational pull between the two. This orbit appears as a curved trajectory from our perspective on Earth.
