Visible light spans from about 760 to 380 nanometers in wavelength, which is the same as about 430 terahertz to about 750 terahertz. The low-frequency end corresponds to light that we perceive as the color red. The high-frequency end is related to light that we see as violet.
Jaguars vary quite widely in weight. The normal range might be 56-96 kilograms (124-211 pounds). Big males can weigh 159 kilograms (350 pounds), and the smaller cats can weigh as little as 36 kilograms (80 pounds). Males are typically 10 to 20 percent larger than the females. A link to the Wikipedia article on the jaguar is provided.
Mass and weight example - the moon. In the below example, we've featured an astronaut on earth and on the moon. The Moon's gravity is much less than the Earth's gravity - approximately one sixth. So, a 100 kg astronaut weighs 980N on Earth. On the Moon, the astronaut would weigh only 162.2N. However, the astronaut's mass is 100kg where-ever they are. Weight on Earth: 100kg x 9.8m/s2 = 980N. Weight on Moon: 100kg x 1.622 m/s2 = 162.2N.
