A centripetal family is one that binds members together and keeps family members tightly associated with the family system.
Substitute "photon" for "ray" and it's one. One photon falling on a plane mirror will come back off of the reflective surface if that reflective surface does not absorb it. (In a perfect plane mirror, every photon that falls on the surface will be reflected.) A photon does not "create" a second photon in a reflection event.
The energy of a photon is inversely propotional to its wavelength. The wavelength of a blue photon is less than that of a red photon. That makes the blue photon more energetic. Or how about this? The energy of a photon is directly proportional to its frequency. The frequency of a blue photon is greater than that of a red photon. That makes the blue photon more energetic. The wavelength of a photon is inversely proportional to its frequency. The the longer the wavelength, the lower the frequency. The shorter the wavelength, the higher the frequency.

the mass of a photon is zero
9 members in the weasly family
How many members are in James cook's family
she has 3 family members
Thomas Edison had 20 family members!
7
IT DEPENDS HOW MANY FAMILY MEMBERS ARE THERE. if there are 24 family members , they could play 11 sports
Stefano Gabbana has exactly 5 family members!!
she had many family members and was some how related to every god and/or goddess
four members
6 members
Stephanie rice has 8 family members in her family Stephanie rice has 8 family members in her family
