It is a source of light - through bio-luminescence.
yes
A shadow is the absence of light, a reflection is just that, the reflection of light. So a shadow comes from blocking a light source, a reflection comes from the bouncing of light of one source and on to another
a light source and a reflector
I'm not entirely sure, but I think it's the angle of reflection.
Yes - the luminescence is produced by a chemical reaction within the insects body.
You will because a boy firefly light ups while the girl wont light up
you can demonstrate total internal reflection using a light source and glass gratings.
When a ray of light is shone at a mirror, it will be reflected following the law of reflection, where the angle of incidence is equal to the angle of reflection. The reflection will produce a mirror image of the object or light source.
One common source of error in a reflection experiment is not positioning the mirror or reflective surface perfectly perpendicular to the incident light source, resulting in an inaccurate angle of reflection. This can lead to errors in measuring the angle of reflection and calculating reflection properties like the law of reflection. Regular calibration and ensuring proper alignment can help minimize this error.
A star is a massive celestial body that emits light and energy through nuclear fusion. A firefly is a small insect that produces bioluminescence to attract mates or prey. The main difference is in their size, nature, and source of light production.
The example of a firefly producing light involves the transformation of chemical energy (from its food) directly into light energy through a process known as bioluminescence. This chemical reaction occurs within the firefly's body and results in the emission of light without the need for an external light source.
Firefly gets it's light by what is called as bioluminescence. In this phenomena, you get the light generated by animal, plant or some types of microorganisms. Here you get the light generated without production of the heat. In case of firefly you get the light intermittently. So that the the partner should be spotted, when light is on and the risk of being caught by the predator is reduced, when the light is off.
