I think you mean leader not leather. One Direction is a band and all the members are important. But most say Harry Styles is the leader.
Because that's the day they formed.
because they chanched the lifes of many people in the whole world
Harry - Cats Niall - Food (specifically Nandos) Zayn - Mirrors for looking at himself Louis - girls who eat carrots and drive a Lamborghini Liam - Forks (he is scared of spoons)
It is season 6 episode 4 and it's called iGo one direction
Mirrors on either end select the proper direction -one is 100% reflecting -one is partially transparent.
The light bulbs in flashlight are not powerful but the mirrors inside help reflect the light that is not directed in your direction
kaleidoscope?????
By something called reflection.
A periscope works using two mirrors placed at 45 degree angles and in the direction you wish to see. A periscope uses the two mirrors to bounce light from one place to another. The light comes through the lense, bounces off one mirror to the other and then into the person's eye.
mirrors
the most important part is the bronzed mirrors
Concave mirrors are used because they will reflect a light source inside the curve in one general direction. To be more specific, the mirrors are close to parabolic. Parabolas have the property that light beams generated at the focal point of the parabola are all reflected parallel out of the mirror.
Sure; mirrors, lens, prism, change of medium.
It is important to look over one's shoulder and use the rear view mirrors when backing up in a motor vehicle because one has to look for objects or humans behind the vehicle so that he or she does not drive into those.
Because it collects and focuses as much as possible of the light from the bulb and send it out as a fairly tight beam in one direction only.
they are made out of reflective material, and just reflect in a different direction
