Blue light, shorter wavelength, brighter

Explanation:

The color of a beam of light depends on the wavelength of the light

The wavelength of blue light is short and ranges from 450 nanometers to 495  nanometers, while the the wavelength of red light is longer and ranges from 620 to 750 nm

However, the energy of the photons that produce red light are lower than those that produce blue light, therefore, blue light have higher radiant energy, and is therefore, brighter than red light

Therefore;

Blue light have shorter wavelength, (and it is) brighter (than red light, when produced from a given area)

for this one it would be d bump/forearm pass

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length
