What are surfaces that reflect/block/weaken UV rays and why are they able to do that?
Why not just ask your Mum. Ok so there are about four different ways one lights an oven. 1. Some ovens have an electronic ignition. When you push down on the temperature control knob and turn it, the electronic ignition will start making a snapping noise as it makes a spark at the burner which lights it. When you let go of the knob after you set to your desired temperature, the electronic ignition stops making the spark. 2. Some ovens have a pilot light which is on all the time. It is a very small flame that is there so that when you push down on the temperature control knob and turn it, the little pilot flame lights the main burner. 3. The oldest of the old fashioned ovens had only one way to light it and that was the cook opens the oven door wide. Light a match and put it near the burner. Then push down on the temperature control knob and turn it to turn the gas on. The flame of your match will light the oven. This is the most unsafe type oven and isn't found too often anymore, but just in case there you have it. Always light the match first BEFORE turning on the gas. 4. The forth way to light your oven is to ask you Mum.
