Ahigh school website directs parents to not allow student access to blue laser pointers or allow the students to bring them to school. it includes a video describing the danger inherent in the misuse of all laser pointers particularly the blue laser pointer. why would they claim that blue laser pointers are more of a concern than red laser pointers?

Primarily because of the higher energy of blue light than the red light.

Explanation:

Light is formed of photons, each one exhibiting an energy equivalent to E = hf, here h refers to the Planck Constant, and f is the frequency of the light. The frequency of blue light is 650 Hz, while the frequency of red light is about 450 Hz. The higher energy signifies higher energy, thus, blue light is more energetic in comparison to red light, and hence, can result in more destruction than red light.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
