If Bernoulli's equation P + 1/2ρv2 + ρgh = constant, implying that pressure decreases as velocity increases, and the Venturi effect states that a1v1 = a2v, what resolves this apparent contradiction? The velocity slows as the cross sectional area increases, but a narrower pipe would have greater...
Googling is nice, but I like direct answers to questions (which you all have been kindly providing!) This isn't homework, just me trying to understand the concepts better.
Is there any way to hold the spoon near a wall so it does? Or is some other method needed?
I don't either, it's just something to accept without proof and hope everything reconciles later on. A common but suboptimal learning technique :O
How do I draw the ray diagram? Measure the object and...
Great info everyone, thanks. So the eye can't tell the difference. A movie is a real image, while a mirage is virtual. A plane mirror is always upright and therefore virtual: the source of light is in front of the mirror but it appears in back. Does the curvature reflect the light more than...
Is there a simple way to determine or prove this? Real images are always inverted, and unlike virtual images can be projected onto a screen (I'm not even sure what this means to be honest). If I look at the back end of a spoon (convex mirror), the image is always upright and therefore virtual...
