Через красный светофильтр надпись не прочтете! Красный цвет воспринимается потому, что отражает только лучи красного цвета из всего спектра. Через красный светофильтр тоже пропускает только красные лучи, отраженные и от белой бумаги и от красной надписи, т. е. , вся бумага и надпись будут одинаково красными!!

Нужен смысловой перевод текста
One winter evening a country shopkeeper was about to close his shop for the night. He went outto shut the windows from outside and through the glass he noticed that a man in the shop quickly took a pound of fresh butter from a shelf and hide the in his hat."What fun I'll have", the shopkeeper said to himself as he thought of a way to punish the man for stealing.
"I say, Seth," said the shopkeeper, as he came in and closed the door after him.
Seth already had his hand on the door, ready to leave the shop as quickly as possible.
"I say, Seth, sit down. On such a cold night as this, it is very pleasant to sit in a warm room."
Seth did not know what to do. He had the butter in the hat and wanted to get out of the shop at once. But the shopkeeper took Seth by the shoulder and made him sit close to the stove.
"We'll make it a little warmer, Seth," he said as he opened the stove door and put some sticks inside. "If you are not warm enough you'll freeze when you go out on a night like this."Seth already felt the butter melting, and he jumped up and said he must go.
"Not till you are quite warm, Seth. I'll tell you a story," said the shopkeeper as he made Seth sit down again.
"Oh, it's so hot here," said Seth.
"Sit down, don't be in such a hurry."
"But I must go. My cows... they're hungry... I must go and feed them."Don't hurry, Seth, let the cows take care of themselves."
Poor Seth! He didn't know what to do. The butter began to melt and came pouring from under his hat down into his eyes and mouth.
The shopkeeper was talking as if nothing was the matter and continued to put sticks into the stove.
"Fine night this," he said. "Seth, why don't you take your hat off? You seem to be warm. Let me put your hat over here."
"No!" cried poor Seth at last. "No! I must go! Let me go out. I'm not well. Let me go!"
The butter was now pouring down the poor man's face and neck and even down his body into his boots, so that he was in a perfect bath of oil.
"Well, good night, Seth," said the shopkeeper smiling, "if you really want to go." Then he added, as Seth made his way to the door, "I say, Seth, I think the fun I have had out of you is worth ninepence so I shan't charge you for that pound of butter in your hat."-
