- You can see your lecturer in class (if you are there) because They emit visible light They reflect visible light O They emit infrared radiation O They reflect infrared radiationAbout how fast does light travel through empty space? Group of answer choices Light cannot travel through empty space. 300 million meters per second 186 million miles per second 300 million kilometers per hourIn the United States early cell phones used a band of frequencies around 800 MHz. (Now more bands are used, ranging from about 700 MHz to 2000 MHz.) What is the wavelength of an 800 MHz light wave?
