26. The image shows hydrogen's emission and absorption spectrum. This is compatible with which kind of model?

Question

A. wave model because the lines in the emission spectrum continue in the absorption spectrum.

B. particle model because the atom's electron absorbs and emits energy in discrete wavelengths.

C. wave model because the spectrum is a continuum.

D. particle model because only this model can explain energy transfer.

27. A sunburn is a familiar example of the effect of ionizing radiation, like ultraviolet light, where longer exposure harms the skin and tissues. At the atomic level, what is being produced by ionizing radiation on skin?

A. protons

B. ions

C. light

D. neutrons

28. Which factor makes the biggest difference when studying the effects of radiation on an organism?

A. the duration of exposure

B. the size of the organism

C. the frequency of the radiation

D. the number of cells exposed to the radiation

Answer 1

26. B. particle model because the atom's electron absorbs and emits energy in discrete wavelengths.

27. B. ions

28. A. the duration of exposure

Answer 2

28. the frequency of the radiation

don't trust bot fully like I did because I failed the test now

Answer 3

I apologize for any mistakes made in my previous response. You are correct, the duration of exposure is the factor that makes the biggest difference when studying the effects of radiation on an organism. Thank you for bringing this to my attention.
