Answer:
The arrows always start at the magnet's north pole and point towards its south pole. When two like-poles point together, the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up. So the magnets will push apart (repel).
B- at night
In eyes of the humans, and many other animals there are two types of receptors, the rods, and the cones. The cones have an important role in color vision and they possess different types of pigment which enable color vision.
On the other hand, the rods are more sensitive to light, and they are responsible for black and white vision.
Therefore, an increase in the number of rods can enable the animal to see betther in the dark.
Answer:
Diffraction and Interference of light support the wave theory of light.
Explanation:
Complete Question
Which phenomena support only the wave theory of light? Check all that apply.
1.reflection
2.refraction
3.diffraction
4.interference
5.photoelectric effect
Solution
There are two theories/schools of thoughts that light possesses wave and particle properties.
The wave properties of light explain that light is made as a result of interactions of electric and magnetic fields, hence, light is regarded as an electromagnetic wave that propagates without the need for a material medium and moves in a direction perpendicular to the direction of the oscillations or direction of the cause/source of the light waves.
Properties that support the wave properties of light are diffraction (ability to navigate or bend around obstacles) and Interference (two light waves can combine or superimpose to form a single resultant light wave with amplitude greater, lower or equal to the amplitudes of the two constituting light waves).
