Question

d. longer mul polon of that light. e. heavier prio 2. Arrange these light rays in the order of increasing wavelengths: radio waves =uw microwaves _infrared - gamma rays 3. Briefly describe what happens to light quality when an object Xrays —_visible light a. absorbs light b. reflects light c. transmits light 4. What does an object colored "green" does to the quality of light that hits it? How about an object colored "black" or "white"? 5. Describe the absorbance spectra (a graph of pigment absorbance vs. light wavelength) of chlorophylla and b. 6. Based on the absorbance spectra of chlorophyll a and b, , which two colors and wavelengths in nm) of the visible light are most useful as energy source for light dependent reactions of photosynthesis?

Answer 1

Note: Only the first four parts/questions can be answered at once. Therefore, question 02 and 3 parts of question three has been solved properly.

Question 02

Answer: Numbering the light rays from the lowest wavelength (No 01) to highest wavelength (No 02)

• Radiowaves: 06 ( 1 mm)
• Microwaves: 05 (1 mm - 25 μm)
• Gamma rays: 01 (<10^-12 m)
• Visible light: 04 (750 nm - 400 nm)
• UV: 03 (400 nm - 1 nm)
• Infrared: 05 (25 μm - 2.5 μm)
• X rays: 02 (1 nm - 1 pm)

Question 03:

Answer:

part a

Absorbs light: When light is absorbed then the light would selectively absorb and reflects or transmits light to certain frequencies.

part b

Reflects light: When light is reflected it leaves that surface in a specific direction or in very many different directions.

part c

Transmits light: When light is transmitted from an object it would be either reflected or absorbed or refracted.
