Describe what will happen to the wave as it goes through the hole. what do we call this?​
kari74 [83]

Diffraction occurs when a wave moves through an opening in a barrier. This causes the wave to change direction and spread out.

Waves can behave in three different ways depending on the obstacles they encounter. They can reflect, refract or diffract. In diffraction, waves such as sound, light or water either bend around small objects that obstruct their passage or spread out as they travel through a gap in the barrier.

The degree of diffraction forms a direct relationship with wavelength. It generally increases as wavelength increases. Conversely, the amount of bending lessens as wavelength decreases. However, if the opening of the barrier is smaller than the wavelength, the effect of diffraction is not easily observed. Hope this helps.

Lh is released by the anterior pituitary gland to stimulate sertoli cells to produce sperm. (lo 13.2) true or false
harina [27]
This is false for a number of reasons. While LH (which stands for Leutinizing Hormone) is released by the anterior pituitary gland and can be present in both females and males, it play a more predominant role in females. Working closely with FSH (Follicle Stimulating Hormone) a surge in LH begins the process of ovulation and the development of the Corpeus Leuteum.

In Males it is used both for the production of sperm but to stimulate the production of testosterone.
