HELP!!
Question 1: Sound wave have a velocity in air of about 330 m/s, and range in frequency from about 20 hz to 20khz. explian why the diffraction of sound is more evident in everday life than the diffraction of light.
Question 2: You are standing outside a sound proofed room, one metre to the side of the door to the room. The door is open. A TV is playing in the room. Explian why you can hear the TV but can not see it
Can anyone help me to explian these 2 physics questions?
Thankyou
回答出色的，追加分数！！！！
希望用物理公式和代数进行解释。
如可以用英语解释的，那最好了！！！

问题1: 声波有速度在大约330 m/s 里空气, 和范围在频率从大约20 赫兹对20khz. explian 为什么声音的衍射比光的衍射是显然的在日常生活中。
答：这是因为光波的波长较短,它比衍射物线度小得多之故.如果障碍物尺度与光的波长可以比较时,就会看到衍射现象.具体的可以参照书本一些波长数据。
问题2: 您站立在一间酣然的被照明的屋子, 一米之外对门的边对屋子。门是打开的。电视在屋子里。Explian 为什么您听见电视但不能看它？
答：不知道。呵呵！可能是因为室内的光线太强，光波比电视发出的波长，所以你就看不到电视了！
或许电视屏幕没有朝着你。
