1
Q
Voltage as the force required to move 1 coulomb through a resistance on 1 ohm in 1 second
A
what
2
Q
Max occurs when
A
Receiver aligned in same plane of polarisation as wave
3
Q
Initially air resistance is in the same direction as weight
A
wow
4
Q
Stuff idk diffraction
A
Easier to see stars w telescope as lens it a lot larger then human eye lens, so less diffraction more resolved image
Greater wavelength wider fringes
Narrower slit makes fringes wider
5
Q
Why microscopes use higher voltage
A
Increases resolution as electrons have more speed – lower db wavelength, so are diffracted less
6
Q
3 Things needed to accept a new scientific idea
A
Testable idea
Mathematical proof
Experimental evidence
7
Q
A
