Birds & bees (ultraviolet light waves), snakes (heat waves) and I don't know a 4th.
If you can see it, it is visible. If you cannot it is not visible. Quite simple, really.
I'm assuming by "waves" you mean "electromagnetic waves," since there are ocean waves and a few other waves that we can see too. We can also perceive sound waves, but cannot see them. The electromagnetic waves that we can see are called the "visibile lights." Their wavelength range from about 760 nm( 760*10^-9 m), bright red, to about 390 nm, bright violet. Their frequency range from about 4*10^14 Hz to 7.9*10^14 Hz, respectively. Infrared and Ultraviolet are NOT a part of visible light. No he means waves in the sea
It is a heat wave that occurs, on average, only once in 5 years. The other 4 years will not see heat as severe as that.
insects see ultravioletreptiles see ultravioletbirds see ultravioletpit viper snakes see infrared with their "pits" (not their eyes)Mammals other than primates can only see red and blue.
Yes they can see, smell, taste, hear, feel, and they can sense
Our moon is the only moon visible from earth with the naked eye. With a good personal telescope, it is possible to see 4 of Jupiter's moons.
The shortest wavelength of visible light for your eye is the wavelength of the lastcolor you can see on the blue end of the rainbow. It may be slightly different forsomeone else's eye.
The feotal pole is not visible until week 6-6,5 and it is not uncommon it's not visible until week 8.
The period of a 4 Hz wave is 0.25 seconds. Period is the time it takes for one complete cycle of a wave to occur. In this case, for a 4 Hz wave, the wave completes one full cycle every 0.25 seconds.
There are currently 4 animals that live in Siwa: The Desert Fox, the Desert Dear, the Desert Rat, and the Desert Bird You will be lucky to see such as these animals with your eyes, as these animals are so extinct
The frequency of the wave is the reciprocal of the period, so in this case, it would be 1/4 Hz.
