The sky appears to be blue during the day because: 1. Air absorbs blue light less than other frequencies (i.e., acts like a blue filter). 2. Air molecules emit blue light after being struck by sunlight. 3. The sky reflects blue light from the oceans. 4. The temperature high in the Earth's upper atmosphere is 1000 K. 5. None of the above.

11. the question with all details is in the image 11. How long would it take you to hear an echo if a canyon wall is 803 meters away. (velocity of sound in air = 343 m/s)
Describe 2 ways that waves can interact with physical boundaries to their medium?
The planet Venus is different from the earth in several respects. First, it is only 70% as far from the sun. Second, its thick clouds reflect 77% of all incident sunlight. Finally, its atmosphere is much more opaque to infrared light. Estimate the surface temperature again, taking the reflectivity of the clouds into account.

(Vo =331 m/s) 3- Rarefaction is a state of low particle density and low air pressure. (TRUE OR FALSE)
26.) Waves with differing amplitiudes can be best described by which of the following statements?a. Waves with different amplitudes have different energies. b. Waves with different amplitudes have the same amount of energy. c. Waves with different amplitudes have different wavelengths.
the wavelength of a wave refers to the length of the repeating pattern of crests and troughs long wavelength waves have crests that are spaced relatively far apart. short wavelength waves have crests that are relatively close to cach other. use the controls to determine two ways to increase the wavelength of the waves. describe what you did to increase the wavelength.
Why is the sky blue at midday?-There is a large amount of water in the air and water is blue, so the sky is blue.-Interstellar dust particles interacting in the upper atmosphere cause a cascade of red, green, and blue light, but only the blue light is bright enough to reach the Earth's surface. -Light is scattered from molecules in the sky. The molecules resonate most strongly at higher frequencies/lower wavelengths, so the greatest intensity of scattered light is at the blue end of the spectrum.-Light is scattered from molecules in the sky but only the blue light reaches the Earth's surface.
